Research of TiO 2 additive effect on dense forsterite synthesis

The effect of TiO2 additive on the synthesis of dense forsterite is investigated in the present work. As the intermediate phase formed in the synthesis process, the magnesium titanate plays a very important role in the improvement of the formation and densification of forsterite. Notably, it finally transfers into a high melting point second phase when segregated at a higher sintering temperature. The addition of TiO2 improves the density of forsterite at a low temperature by liquid-phase sintering and may reduce or even eliminate the defects of liquid phase-sintering by the segregation of the liquid phase at high temperature.
