在用碳热还原法制备AlN粉末过程中,发现大量白色AlN晶须存在于AlN粉末坯体表面,其形貌有直板状、锯齿状及扭曲状,电子衍射花班显示结晶方向均为[0002],其生长机理可能为VS机制.

In the process of manufacturing of the AIN Powders by carbothermal reduction method, thewhiskers have ben found on the surfaCe of AIN powder pellets. The whiskers have ben confirmed to be AINwhiskers with Planar, serrated morphologies by EPMA, XRD, TEM, a
