Effect of Adding Phase on the Properties of ZrB2 Based Ultra-high-temperature Ceramics

摘要：

　　ZrB2 belongs to a class of ceramics defined ultra-high-temperature ceramics with extremely high melting temperatures.To make ZrB2 ceramics possess the high relative density and the better oxidation resistance.The results show YAG and Al2O3 help for the densification of ZrB2 based ceramics.The oxidation layer thickness of sintered ceramics adding YAG or YAG-Al2O3 phase is thinner than that of sintered pure ZrB2 ceramics under the same oxidation condition,the oxidation layer thickness ofsintered ceramics adding YAG-Al2O3 phase is thinner than that of sintered ceramics adding YAG phase,the oxidation layer thickness of sintered ceramics is decreased with an increased Al2O3 content.
