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.
