A Study of the Phase Relations of ZrO2–TiO2 and ZrO2–TiO2–SiO2

Abstract

The phase relations of the systems ZrO2–TiO2 and ZrO2–TiO2–SiO2 were investigated. X‐ray diffraction techniques served as the principal means of analysis. The binary system ZrO2–TiO2 was found to be one of partial solid solutions with no intermediate compounds. A eutectic point was found to exist at 50 to 55 weight % ZrO2 and 1600°C. A preliminary investigation of the ternary system ZrO2–TiO2–SiO2, although not extensive, resulted in a better understanding of this system, with a fairly accurate location of some of its boundary lines. A eutectic point was located at 2% ZrO2, 10% TiO2, and 88% SiO2 at approximately 1500°C.
