稻壳合成β-SiC晶须的中试研究及产品分析

Pilot Synthesis of β-SiC Whiskers from Rice Hulls and Product Analysis

本文对稻壳合成ＳｉＣ晶须（简称ＳｉＣｗ）的烧结中试进行了研究，验证了两种催化剂制度下的生产工艺，生产出两种形貌、结构特征不同的ＳｉＣｗ，并同美国、日本生产的ＳｉＣｗ在形貌结构、杂质含量等方面进行了比较。研究表明：中试生产的稻壳ＳｉＣｗ质量达到了国外同类产品的水平。

The pilot experiment of SiC whiskers(SiCw) sintered from rice hulls is studied in this paper.The technology with two types of catalysts is demonstrated,and two kinds of SiCw with different morphology and structure properties are produced.Compared with the SiCw produced in USA and Japan for morphology,structure and impurity content,the SiCw produced by this pilot plant reach the same level.The growth mechanism of SiCw is also studied.
