Limits of ternary solid solutions in the system Cg203-Zr02-Si02

Abstract

The best in refractory stability are the masses consisting of oxides forming solid solutions. The absence of eutectics that cause premature softening and deformation at relatively low temperatures makes solid solutions of oxides a valuable highly refractory material. From this point of view, the regions of solid solutions in the Cr203-Zr02-Si02 system characterized by high melting temperatures are of considerable interest. The existence of ternary solid solutions in this system made us assume the existence of solid solution regions in the double systems Zr02-Si02 and Cr203-Zr02.
