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. |
