摘要
The sintering and microstructure development of magnesia containing 0-10wt% TiO2 at temperatures in the range 1300-1600 degrees C have been investigated. The addition of TiO2 markedly promoted densification at relatively low temperature, and grain growth. Excess TiO2 over the solid solubility limit of TiO2 (0.3 wt%) reacted with magnesia to form inter- and intra-granular magnesium titanate (Mg2TiO4) above 1300 degrees C. The grain size of MgO increased with increasing TiO2 content, and densification was mainly governed by MgO grain growth. (C) 1998 Kluwer Academic Publishers.
