摘要：

Zirconium diboride (ZrB2) is difficult to prepare as high-density ceramics, which limits its application. To obtain high-density ZrB2 ceramics for improving its high-temperature properties, ZrB2 particles were coated with Al2O3-Y2O3 particles to prepare 20% YAG-ZrB2 ceramics with SPS. The optimum sintering condition is a temperature of 1700 degrees C, a pressure of 20 MPa, and a holding time of 4 min. The relative density of prepared 20% YAG-ZrB2 multi-phase ceramics is 97.2% under optimization sintering technology, which indicate that high density YAG-ZrB2 multi-phase ceramics are successfully prepared.
