Physicochemical study of the binary system Сr2O3 — MgO (To the problem of finding new highly refractory materials)
Abstract
Among the refractory materials currently in use, chromite iron ore and magnesite deserve special attention. But, as is known, these refractories in their pure form are not stable enough and are destroyed relatively quickly, which causes frequent repairs of the internal lining of smelting furnaces. Therefore, the study of the dependence of the melting temperature on the composition of mixtures of highly refractory materials, in particular the determination of the areas of formation of solid solutions, is one of the ways to find new highly refractory materials. This prompted us to study the melting diagrams of the systems: Сr2O3 — MgO и Сr2O3 — ZrO2.
