Description

The processes of mineral formation and the features of the structure of fused-cast refractories of the Cr2O3-Al2O3-ZrO2-SiO2 system by the methods of X-ray phase, petrographic and microprobe analyses are investigated. The X-ray diffraction analysis of synthesized chromalumozirconium refractories revealed the presence of two basic phases - Cr2O3 solid solution in Al2O3 and baddeleyite - ZnO2. Chromium oxide in a form of a separate phase is not revealed. It has been found that the structure of the investigated samples, is not totally crystalline. The analysis of phase interrelations in refractories permitted to establish the order of melt crystallization
