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.
