Phase equilibria in the SiO2TiO2 binary and the effect of TiO2 on the α-β transformation in cristobalite

Abstract The solid solubility of TiO 2 in cristobalite at 1450°C is ∼4.7 wt%. The variation of the lattice constant and of the α-β transformation temperature of cristobalite with increasing TiO 2 content was also studied.
