| 摘 要： | 采用纳米Ａｌ２Ｏ３粉和纳米ＺｒＯ２（３Ｙ）粉为原料，对不同成分配比的Ａｌ２Ｏ３－ＺｒＯ２（３Ｙ）复相陶瓷进行了微波为烧结的研究。实验结果表明微波烧结可获得委肮的致密度，并提高断裂韧性，但晶粒长大倾身大于其它烧结方式；在Ａｌ２Ｏ３－ｚｒ２（３Ｙ）二元系中，随ＺｒＯ２（３Ｙ）含量啬，烧结时的致密化过程加速，且晶粒长大倾向减小。 |

| Abstract: | In this paper, nano Al 2O 3 powder and ZrO 2(3Y)powder were used as raw materials for microwave sintering of Al 2O 3-ZrO 2(3Y) multiphase ceramics of different components. The experimental results show that microwave sintering enables Al 2O 3-ZrO 2(3Y) multiphase ceramics to have high density and fracture toughness and also produces coarse grains easily. In Al 2O 3-ZrO 2(3Y) ceramics, the process of densification by microwave sintering becomes short with the increase of ZrO 2(3Y) mass fraction, and the grain_size of this ceramics decreases also. |
