Abstract

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.
