Phase relations in the system ZrSiO4-TiO2 was investigated at temperatures between 1050° and 1600°C by a quenching method. There were 3 solid phases in this system, namely ZrSiO4, TiO2ss, and ZrTiO4ss. ZrSiO4 was decomposed to ZrO2 and SiO2 by the abbition of TiO2. TiO2ss was formed up to 4wt%, 10wt%, 20wt%, and 26wt% of ZrSiO4 at 1050°C, 1200°C, 1400°C, and 1600°C respectively. ZrTiO4 appeared above 1400°C. The dissociated silica existed as cristobalite below 1500°C and changed into liquid above 1550°C.
