WO3 ADDITION, CRYSTAL PHASE EVOLUTION AND PROPERTIES OF Y2O3-DOPED ALN CERAMICS

The effect of WO3 addition on the densification, phase evolution, and properties of Y2O3-doped AlN ceramics sintered at 1800oC for 3 h was investigated. The total amount of oxides added was 4.5 wt. %. In all of the compositions investigated, YAlO3 and Y4Al2O9 were observed as the secondary phases. W...
