A complex of physico-chemical studies was carried out: X-ray phase analysis, differential thermal analysis, chemical analysis of vanadium production waste. It has been established that these wastes containing 17.39 % Mn2O3 in their composition are promising raw materials for the production of volumetric wall ceramics. The effect of heat treatment at 200, 500, 600 and 700 ?C on the phase composition of vanadium production waste has been studied.
