Fabrication of HAp–ZrO2 (3Y) nano-composite by SPS

Nano-HAp–ZrO2 powders and HAp–TZP(3Y) composites have been fabricated in this work. The results show that nano-HAp–ZrO2 powders with homogeneous distribution could be synthesized by two-step precipitation method. HAp–TZP(3Y) composites with small grain size could be sintered at relatively low temperatures and very short dwelling time by using SPS technology. No reaction between HAp and ZrO2 was found, which could be attributed to the very short sintering time of SPS.
