Abstract

Changes in structure, phase composition and crystal structure parameters are studied for materials of the ZrO₂–MgO system after cyclic thermal shock effects. Features are revealed for formation of ceramic structure and phase condition with implementation of internal stresses connected with a sharp change in temperature. Optimum compositions are established for refractory materials based on ZrO₂ answering high specifications for thermal shock resistance and refractoriness.
