Abstract

In order to decrease the oxidization and improve the strength of ZrB 2 at high temperature, the surface of ZrB 2 was coated with Al(OH) 3 and Y(OH) 3 to synthesize Al(OH) 3 -Y(OH) 3 -ZrB 2 composite particles. Through TEM, EPMA and SEM analysis, when pH was about 9, Al(OH) 3 -Y(OH) 3 -ZrB 2 composite particles were successfully synthesized by co-precipitation methods. The coating layer was about 25 nm, which has compaction and conformability. Dispersibility of coated ZrB 2 with Al(OH) 3 and Y(OH) 3 particles were very good. Synthesis of Al(OH) 3 -Y(OH) 3 -ZrB 2 composite powder will lay the foundation for preparing high-performance YAG/ZrB 2 and Al 2 O 3 -YAG/ZrB 2 multiphase ceramic materials.
