Abstract

This paper focus on the effects of the additions of MgO and TiO2 on the various properties of Zirconia-Toughened Alumina ceramic composites made of electro-fused zirconia. The results show that at 1643 0C, the compactness, strength and hardness of Zirconia-Toughened Alumina ceramic materials can be improved when the respective addition amounts of MgO and TiO2 are 0.5%. But the comprehensive performance of Zirconia-Toughened Alumina ceramic materials are greatly improved when the total content of both is 1%. After mixing the powders and washing with sand for 1 hour, the comprehensive performance of Zirconia-Toughened Alumina composite ceramic is optimal, which the density, hardness, and flexural strength are 4.36g.cm-3, 73HRC, and 391MPa respectively.

Keywords
