Effects of TiO2 on the sintering and microstructure of zirconia-toughened-alumina (ZTA) composites were investigated. The starting materials were α-Al2O3 powder, Zr(OC3H7)4 and Ti(OC3H7)4. Experimental results indicated that TiO2 additive has a significant effect on the coalescence of ZrO2 particles as well as on the formation of a crystalline phase of ZrO2. TiO2 promotes the sintering of ZTA powders and the grain growth of Al2O2 and ZrO2 with more pronounced effect at higher TiO2 contents.
