SOL-GEL SYNTHESIS IN THE CaO-Al2O3 SYSTEM USING ALUMINA-CONTAINING WASTE

Abstract

The article determines the optimal synthesis temperatures and methods of using alumina-containing waste in the process of solid-phase formation of crystalline structures of tricalcium aluminate. It has been established that the optimal synthesis temperature by the sol-gel method is 1100 °C and corresponds to the most complete formation of tricalcium aluminate with the smallest particle dispersion, size in the range of 100-700 nm.
