摘要
研究了经过两种不同压力１５．７ＧＰａ和２５．６ＧＰａ的冲击波活化的Ｓｉ３Ｎ４粉末的表观和显微特性及其烧结特性。结果表明冲击波活化在烧结过程中有明显的增进密实化进程的作用。
In this paper,we have studied the surface and microscopic features of the silicon nitride powders,which have been activated by shock waves in two pressures:15.7GPa and 25.6GPa,and the sintering features of the ceramics sintered from the activated powders.The results show that the shock activation play an apparent role on promoting densification of the powders during sintering.
