| 摘 要： | 采用了三种复合添加剂Y2O3-CaF2、Y2O3-Dy2O3和Y2O3-Li2O,在1 650℃热压烧结AlN陶瓷;测定、分析了AlN陶瓷的性能和微观结构。结果表明,添加该三种复合助剂在低温烧结的AlN陶瓷晶格氧含量均较低,样品热导率较高,尤其是添加复合助剂Y2O3-CaF2可获得热导率为192 W.m-1.K-1的AlN陶瓷样品。

| Abstract: | AlN ceramics doped with Y2O3-CaF2?Y2O3-Dy2O3 and Y2O3-Li2O were sintered at 1 650 ℃.The properties and microstructure of hot-pressure sintered AlN ceramics were measured and studied in this paper.The results show that AlN ceramics sintered in this way have a lower oxygen content and higher thermal conductivity.The thermal conductivity of AlN ceramics,especially doped with Y2O3 and CaF2,is as high as 192 W/(m·K). |
