Development of optimal modes of mechanochemical treatment of technogenic raw materials with various modifiers to produce heat-insulating materials Bakhtiyar Sadykov, Ainur Khairullina, Aida Artykbayeva, Alua Maten, Anar Zhapekova, et al. Pure and Applied Chemistry, 2026 This paper presents the results of studies on the effect of mechanochemical treatment (MCT) and modification of technogenic waste based on ash and fly ash. Mechanical modification was carried out using a laboratory ball mill with the addition of organic modifiers to the system. After MCT, the physicochemical properties of the obtained modified ash and fly ash particles were studied. Heat insulators based on ash and slag after MCT have a noticeable positive effect on its rheological properties, improving its structure and heat resistance. Self-propagating high-temperature synthesis (SHS) samples with fly ash after MCT showed a significant decrease in thermal conductivity, which leads to improved heat-insulating properties. The obtained samples based on technogenic waste are effective heat-resistant and environmentally friendly materials that are superior to many traditional analogues.
Creation of Modified Aluminum Powders with Increased Reactivity for Energy Systems Ayagoz E. Bakkara, Ainur S. Khairullina, Aida B. Artykbayeva, Alua E. Maten, Aizhan O. Nugymanova, et al. Crystals, 2025 Aluminium plays a key role in developing modern energy technologies, from electrical systems to high-energy materials, providing a combination of functionality, economy, and reliability, but the oxide film on its particles reduces the effective reactivity. This work aims to increase the reactivity of aluminum powder by mechanochemical treatment using modifiers. The materials used were aluminum powder of the ASD brand and graphite of the GL-1 brand. The experiment subjected aluminum powder to mechanochemical treatment (MCT) with different graphite contents. It was shown that MCT significantly increases active aluminum content in the powder due to partial destruction of the oxide film on its surface. In addition, morphological analyses confirm the destruction of the oxide, the graphite coating, and the appearance of lamellar structures measuring 0–58 µm. Thermal analysis shows that the primary exothermic peak shifts from 662.6 °C to 653.9 °C for Al + 10% graphite, and the heat released increases by 27%, which means lower activation energy and more complete oxidation. However, at 20% graphite, the thermal gain decreases, since carbon shields the metal areas. Thus, the optimal content is 10% graphite: at this ratio, the best thermochemical behavior of the powder is achieved. The data obtained indicate that the MCT of aluminum powder with graphite effectively increases its reactivity. The resulting aluminum powders with modified particle surfaces facilitate the development of new technologies for the creation of various high-energy solid propellant systems. For rocket engines, preference is given to solid rocket propellant (SRP), which is a mixture of substances (components) capable of burning in the absence of air, producing a large amount of gaseous working fluid heated to a high temperature, providing thrust.
High-Temperature SHS Heat Insulators Based on Pre-Activated Mineral Raw Materials Bakhtiyar Sadykov, Ainur Khairullina, Aida Artykbayeva, Alua Maten, Anar Zhapekova, et al. Crystals, 2024 In this paper, the results of the technological combustion of SHS heat insulators based on mineral origins are presented. It is shown that after mechanochemical treatment of minerals—diatomite—the kinetic characteristics of the combustion process change, providing targeted formation of the phase composition, structure, and properties of the SHS composite. A positive effect of using various modifiers during the MCT of diatomite—the activation of the combustion process—was established. The selection of modifiers provides an increase in the strength of the synthesized SHS composites as a result of the formation of aluminate compounds in the synthesis products, and a decrease in thermal conductivity to 0.157 W/m*K due to the formation of the ultraporous structure of the samples.
