摘要
为降低工业生产高致密度碳化硅陶瓷成本,优化工艺条件,本文对比了机械混合及高能球磨方法制备前驱粉体对陶瓷烧结体的特性影响。详细探讨了制备工艺条件、粉体配比等因素与陶瓷烧结体的收缩率、体密度、失重率等特性的关系。提出了两种方法差异的实质及与之相应的升温程式,为实际生产提供参考。
In this article, two precursor manufacturing ways for silicon carbide ceramics were compared. The relationship between the technological conditions, the composition of precursor for silicon carbide ceramics and the contraction, density and percentage of weight loss of the final product were studied in detail. An explanation for the differences of these two methods was given and the corresponding temperature elevating mode was also proposed. Those results can be used as references for the real industrial applications.
