Abstract

Zirconium diboride (ZrB 2 ) is difficult to prepare as high-density ceramics, which limits its application. To obtain high-density ZrB 2 ceramics for improving its high-temperature properties, ZrB 2 particles were coated with Al 2 O 3 —Y 2 O 3 particles to prepare 20%YAG—ZrB 2 ceramics with SPS. The optimum sintering condition is a temperature of 1700°C, a pressure of 20 MPa, and a holding time of 4 min. The relative density of prepared 20%YAG—ZrB 2 multi-phase ceramics is 97.2% under optimization sintering technology, which indicate that high density YAG—ZrB 2 multi-phase ceramics are successfully prepared.
