The optimal synthesis temperatures and methods of using the alumina-containing waste in the process of obtaining calcium aluminate are determined. It has been established that the optimum synthesis temperature is 1100°C and corresponds to the maximum full formation of calcium aluminate with the smallest dispersion of particles, the size of 100-700 nm.
