    Bijayalaxmi Maharana, Rudra Narayan Mohapatro, Biswa R. Patra, Ranjita Swain, Sunita Routray, et al.
    Canadian Journal of Chemical Engineering, 2026
    The growing emphasis on sustainable materials has sparked interest in biochar as an eco‐friendly coating material. Biochar, a carbon‐rich material derived from the pyrolysis of various agricultural residues, exhibits excellent structural stability, high porosity, and surface functionality, making it a suitable coating material when combined with appropriate binding agents. This study focused on the production of biochar from agricultural crop residues, including sugarcane bagasse, corn stover, and coconut shell, through slow pyrolysis at 550°C with a heating rate of 5°C min −1 for 1 h. Furthermore, the physicochemical characterization of biochar was conducted to assess its compatibility with various binding agents and its suitability as a coating additive. The formulated biochar coatings were evaluated for their adhesion strength, moisture resistance, durability, and mechanical stability. The results demonstrated that a triple‐layered biochar‐based epoxy coating on a metallic surface enhanced adhesion strength and reduced corrosion rate compared to the uncoated substrate when exposed to a 5 wt.% NaCl solution for 60 days. The triple‐layer coating showed less pitting or delamination even after prolonged immersion under NaCl solution, confirming its superior barrier properties and surface protection. The coating delayed chloride‐ion penetration, but once compromised, the underlying mild steel began to corrode. Furthermore, the study highlights the role of biochar in reducing the dependency on synthetic fillers, promoting waste valorization, and contributing to carbon sequestration. The findings emphasize the potential of biochar‐based coatings in various industrial applications, including industrial equipment, construction, packaging, and protective surface treatments, aligning with the principles of green and circular economy.

    Objective: This paper has focused on the preparation of a high-temperature composite material from naturally available beach sand zircon minerals. materials and methods: The materials and methods used in the present investigation are represented in the form of a schematic diagram shown in Fig. 1. Fig. 1 Schematic diagram representing the materials and methods adopted in the present investigation 2.1. Materials Zircon concentrate was procured from Indian Rare Limited (IREL), Chhatrapur, Odisha. The average size of zircon concentrate taken for the experimental study was in the range of - 300+ 100 µm. 2.1.1.Chemicals used Concentrated hydrochloric acid (38% HCl), sulphuric acid (98.0 % pure), caustic flakes (99.9 % pure), and ammonia solution (25 %) were used for the preparation of zirconia minerals from zircon concentrate. Fumed silica was used for the preparation of synthetic zircon. Fumed silica is produced by subjecting silica to extremely high temperatures, resulting in its condensation from vapor into a fine, powdery form [16, 17]. This material exhibits an ultra-fine particle size of 0.014 μm and a significant surface area of (200 ± 25) m²/g. Its bulk density stands at 36.8 kg/m³, while the particle density reaches 2200 kg/m³ [18] and has a very strong thickening effect. All these chemicals were procured from Central Drug House (P) Limited. 2.2Methods 2.2.1.Characterization of zircon concentrate The physical characterizations such as bulk and true density of zircon concentrate were measured by following the standard procedure. The feed sample was packed by shaking in a 1000 ml graduated cylinder. The bulk density was measured by taking the weight of 1000 cc of zircon concentrate. The bulk density value was calculated by taking weight to the volume of the sample. The unit is expressed as g/cm3. The test provides a clear evaluation of particle size and distribution, essential factors that affect the consistency of material flow and determine packaging precision. The true density of minerals was calculated using Eq. 1. True density = (W2 –W1) / [(W4 – W1) – (W3 – W2)] ------------------------------- (1) Where, W1 = Wt. of sp. gravity bottle with lid. W2 = Wt. of sp. gravity bottle filled with sample and covered with a lid. W3 = Wt. of sp. gravity bottle filled up to 1/3 rd volume with sample and remaining with water and covered with a lid. W4 = Wt. of sp. gravity bottle filled with water only and covered with a lid. True density is an important concept regarding metal purity and packaging. The XRF, XRD, and SEM analysis of zircon concentrate was carried out for detailed characterization. XRF analysis was conducted using a Philips PW2440 (MagiX PRO) sequential wavelength-dispersive X-ray spectrometer with a Rh anode tube operating at 4 kW. XRD analysis was carried out by Aeris Research benchtop X-Ray diffractometer equipped with a DOPS2 goniometer with Heidenhain encoders. SEM imaging was performed with a Hitachi VP-SEM S-3400N, offering a high resolution of 10 nm at 3 kV. The instrument has a magnification range of 5x to 300,000x and operates at voltages between 0.3 and 30 kV. The thermal properties of the samples were studied after drying the sample at 200 ℃ for one hour to remove the moisture content. The thermal gravimetric analysis (TGA) was carried out under nitrogen flow, using a PerkinElmer instrument, made in the USA, with a heating rate of 10 °C/min from 50 °C to 2500 °C. 2.2.2.Preparation of zirconia (ZrO2) minerals The zircon concentrate and caustic soda were taken at a 1:1 ratio (by weight) in a nickel crucible [19] and heated at 650 °C for 6 h. After cooling, the sample was washed with water and 10 % diluted HCl. The product obtained was named frit. HCl, 38% concentrated was added to the frit and kept for around 24 h to facilitate the precipitation process [19]. The solution was heated at 90 °C for 10 min. and flocculent (small pieces of filter papers of ~ 5 gm) was added for coagulation. Further 5 mL of H2SO4 was added to form the precipitate. About 5 ml of 25 % ammonia solution was added and filtered further to remove the sulfate as ammonium sulphate. Literature reports the presence of sulphate reduces the grade of zirconia [20]. Hence, the residue was washed five times with water for 10 minutes to remove the remaining sulphate content. Further, the residue was washed two times with 20 ml of ethyl alcohol to remove the traces of gangue particles dried in an oven at 200 °C for two hours, and calcined at 850 °C for 1 h. The calcined products were considered zirconia and further used for the preparation of synthetic zircon. 2.2.3.Characterization of zirconia nanomaterials The XRF, XRD, and SEM analysis of zirconia was carried out for detailed characterization. TEM analysis was also carried out for zirconia particles to see the size range where they lie using Transmission Electron Microscopy. The equipment used has model number: HT7700 and the country of manufacture is Japan. 2.2.4.Synthesis of synthetic zircon particles and preparation of pellet The produced zirconia powder was mixed with fumed silica in a 1:1 mol ratio. The mixture was ground in a mortar properly to get a homogenous mixture. The mixture was kept in an alumina crucible covered with a lid and calcined at 1500 °C in a furnace for 4 h. The stabilizer (yttrium oxide, Y2O3) was added to stabilize synthetic zircon. Figure 2 shows the calcined mixture which was considered as synthetic zircon. Around 20 g of synthetic zircon powder was taken to prepare a pellet by using a 25-ton fully automatic hydraulic press (Model number: HP 15T/25T, Country of manufacture: India) and sintered in a furnace at 800 °C to harden. Fig. 2 Synthetic zircon in crucible 2.2.4.1.Characterization of sintered synthetic zircon pellets Physical characterizations such as water absorption, and apparent porosity of the samples were determined according to the ASTM standards (ASTM, C838-96). To determine the percentage of water absorption, the pellet was immersed in water at room temperature for 30 minutes. The weight of the pellet was taken before and after immersion into water. Then the percentage of water absorption was taken using Eq. 2. {(Wf – W0)/W0} * 100 ------------------------------------------------------------------------------ (2) Where, Wf: Weight of pellet after immersing it in water for 30 minutes W0: Weight of pellet after immersing it in water The Apparent porosity, which is defined as the ratio of the volume of open pores or voids to the total volume of a material, is calculated by using Eq. 3. Apparent Porosity (%) = {(Ws - Wd) ÷ (Ws - Wsu)} x 100……........................................... (3) Where, Ws: Soaked Weight, Weight of pellet after immersing it in water for 30 minutes Wd: Weight of pellet in dry condition Wsu: Suspended Weight, calculated by multiplying its mass by the acceleration due to gravity The relative density or true density of the product was measured using Eq. 1 discussed above. XRD, SEM, and chemical analyses (XRF analysis) of the sample were also carried out. 2.2.4.2. Determination of Electrical Resistance The electrical resistance of synthetic zircon pellet was measured using a 1000 V megger insulation tester (Model number: MIT230-EN, Country of manufacture: India). 2.2.4.3.Measurement of breakdown voltage To measure the breakdown voltage of the synthetic zircon pellet, a setup was prepared at the laboratory. The setup consisted of a transformer oil test kit with a 50 Hz, single-phase AC supply to find the breakdown voltage. Both terminals of the test kit were connected at both ends of the pellet through highly conducting copper metal, and then the voltage was slowly increased. A point was reached, where the increment in voltage broke and it began to drop. The point, where the voltage drops is known as the breakdown voltage of the sample. Fig. 3(a) shows the mixture of zirconia and fumed silica before calculations, and Fig. 3(b) shows the synthetic zircon pellet prepared and sintered. Fig. 3(c) presents the setup for the measurement of breakdown voltage and Figure 3d shows the pellet after the measurement of breakdown voltage. The black mark on the pellet (Fig. 3,d) was the point where the terminal of the transformer oil test kit was connected. The dielectric strength of the insulator was calculated by using Eq. 4, given below. Dielectric strength = Breakdown voltage (kV) / thickness of the sample (mm) -------------- (4) Fig. 3 (a) Mixture of zirconia and fumed silica before calcination, (b) Pellets prepared and sintered, (c) Set up for measurement of breakdown (d) Pellet after the measurement of breakdown voltage 2.2.5.Laboratory scale investigation of insulating properties of the product About 20 g of synthetic zircon and 2% binder (polyvinyl alcohol) were mixed properly to make a homogeneous mixture. About 10 mL of water was added to it under continuous stirring to prepare an emulsified solution. The emulsified solution was applied to glass and stainless steel beakers of equal volume (100 mL). On the outer surface of a glass beaker, the emulsified solution coating was applied and the same beaker was sintered in a furnace at 100 °C for 1 h. Another glass beaker was also taken without performing any coating on it. Around 80 mL of water was filled in both the beakers and the top of these glasses was insulated properly to avoid heat loss. Two beakers were heated at 100 °C for 30 minutes. The inside and outside temperature of both beakers were noted. The temperature at the outer surface of the beakers was measured using a laboratory thermometer. The thickness of the coating was also varied from 0.5 mm to 1.5 mm to verify the effect of coating on the release of heat energy. Beakers with and without coatings are shown in Figure 4 and Figure 5. The same process was repeated with stainless steel beakers to investigate the insulating property of synthetic zircon on stainless steel material.

The design matrix (Table 1) includes three input parameters—Temperature, Time, and % of Yttrium oxide—and one non-linear output response for training, testing, and validation. Root mean square error and correlation coefficients evaluated the ANN model’s performance. Using various architectures, the model was trained with 70% of the data, tested with 15%, and validated with 15%. The Levenberg-Marquardt (LM) backpropagation algorithm, aimed at minimizing mean squared error, was implemented via MATLAB R2016a. Mean square error (MSE) and mean absolute percentage error (MAPE) assessed performance during training and testing, respectively, as shown in Equations 5 and 6. The ANN model structure is displayed in Figure 6. …. ................................................................................

Further, synthetic zircon was prepared by the calcination of zirconia and silica. The product was characterized by examining the water absorption capacity, apparent porosity, dielectric strength, XRD, chemical analysis, TEM, electrical resistance, relative density, and thermal stability properties. The insulation properties were studied by applying synthetic zircon coatings on base materials. The analysis of the results was carried out by using an artificial neural network (ANN). Results: The dielectric strength was found to be 10.2 kV/mm at a temperature of 1500oC. XRD analysis confirmed the occurrence of tetragonal zircon (t-zircon), which is thermally stable up to 1500oC. Conclusion: TEM results confirmed the synthetic zircon to lie in the nano-size range. XRD analysis confirmed that the synthesized zircon retained ~100% of the tetragonal zircon phase even after calcination at 1500°C, indicating excellent thermal stability at that temperature. The electrical resistance of synthetic zircon was found to be in the range of 200-210MΩ. The comparative study confirmed synthetic zircon to have the potential to be used for high-temperature structural and functional applications, including its preliminary use in thermal barrier systems.
