Abstract

Abstract: Tetragonal Zirconia Polycrystals (TZP) with superfine grains and high flexural strength were obtained by adding certain glass additives into Y-TZP powder and sintered at low temperature. The relationship between the density, mechanical properties arid the amount of additives, sintering temperature were investigated. The results show that Y-TZP with 1wt% glass additives can be densifed at 1400℃. The grain size of Y-TZP is 100-200nm and flexural strength can reach 950MPa.

Key words: Y-TZP, low temperature sintering, superfine ceramics
