| 摘 要： | 微波烧结(Microwave Sintering)是一种新型、高效的烧结技术, 具有传统烧结技术无可比拟的优越性. 本文在不添加任何烧结助剂的前提下, 采用高纯微米级氮化铝(AlN)粉, 在1700℃/2h的微波低温烧结工艺条件下制备出透明度较高的AlN透明陶瓷. 分析结果表明, 采用微波低温烧结工艺制备的AlN透明陶瓷晶粒尺寸细小(<10μm), 晶粒发育完善且分布均匀, 晶界平直光滑且无第二相分布, 从而证明用微波烧结可以实现AlN透明陶瓷的低温烧结.

| Abstract: | Microwave sintering is a new and highly active kind of singtering technology which is superior to the technology of traditional sintering. With highly pure AlN powders and without singtering additives, AlN transparent ceramics were obtained by using microwave sintering at 1700℃ for 2h. The result of experiments indicates that the AlN transparent ceramics prepared by this process have fine grain sizes (less than 10μm), uniform grain distribution, and no oxidized phrases. From above analysis, it is proved that AlN transparent ceramics can be sintered at low temperature by the microwave sintering technology. |
