摘要
研究了用表面活性剂有效地分散纳米ＳｉＣ粉体中的聚集体的实验过程，发现分散状态取决于表面活性剂用量、ｐＨ值和浸泡时间。以Ｓｉ３Ｎ４，ＡｌＮ，ＣａＣＯ３和纳米βＳｉＣ为原始粉料，用反应热压法制备了不同ＳｉＣ含量的纳米ＳｉＣＣａαｓｉａｌｏｎ复相陶瓷，并分别对其相组成、力学性能和显微结构等进行了研究。
The experimental process for effective dispersion of agglomerates in nanoSiC powder using the surfactant was studied.The dispersity is dependent on the amount of the surfactant,pH value and the time immersion.0～40%(in mass)SiCCaαsialon nanocomposites were prepared by hotpressing.The phase composition,mechanical properties and microstructure of the composite were studied.
