Prospects for microwave sintering of the composition from waste of the fuel and energy complex

Abstract

Abstract The article considers an option for solving environmental problems associated with high-temperature waste from enterprises of the fuel and energy complex and the metallurgical industry. A technology is proposed for obtaining material from the ash of a thermal power plant, slag waste from metallurgy and a binder from liquid glass by sintering in a microwave field.. Differences in the phase composition, external characteristics and properties of materials obtained by traditional convective firing and sintering in a microwave field are noted. The phase compositions of the fired materials are determined, and the effect of the amount of the amorphous phase on the final properties of the material is noted. The article shows the structures of fractures of materials, shows the difference in the fineness of the structure of the sample based on ash, obtained by convective firing and sintering in the microwave field. Shown amorphous phase between crystalline formations in the structure of the material, marked by X-ray phase analysis. The prospect of microwave sintering of refractory multicomponent compositions in the microwave field to obtain materials is shown.
