| 摘 要： | 将不同量Y2O3烧结助剂加入AlN纳米粉体，进行N2气氛常压烧结。实验表明，AlN陶瓷致密度随Y2O3加入量的增大而增大，Y2O3烧结助剂加入量在1～3wt％时，导热率随温度上升而上升，Y2O3烧结助剂加入量超过4wt％时，导热率反而下降。

| Abstract: | Different amount of Y2O3 sintering aids added AlN nano-powder and sintering in N2 atmosphere. Testing demonstrated： The density of AlN ceramics increase with the amount of Y2O3, When the amount of Y2O3 is at 1-3wt%, thermal conductivity increase with temperature, when the amount of Y2O3 is exceed 4wt%, thermal conductivity descend with the temperature increase. |
