Additions of NiO, CoO, MnO2, Fe2O3, and CuO promote the anatase-rutile transformation and grain growth of TiO2. Additions of Na2O and WO3 retard the transformation and have no effect on the grain growth. The addition of MoO3 strongly promotes the grain growth but has only a slight effect on the phase transformation. Both the grain growth and transformation are promoted slightly by Cr2O3. The transformation is significantly affected by the method of preparing TiO2. The grain size of TiO2 heated in H2 exceeds that of TiO2 heated in O2, in air, in argon, and in vacuum. The rate of transformation decreases with an increase in the partial pressure of oxygen of the atmosphere.
