The results indicated it was very effective to increase the content of SiC whisker by ammoniating silicasol to decrease the particle size of raw powder and increase the space for SiC whisker growth, and by controlling the reaction temperature to mate the formation of SiC be compatible with the growth of SiC whisker.

工作中系统地研究了反应物料和合成工艺对SiC晶须产率和微观形貌的影响，发现氨解能促进硅溶胶的凝胶化，并细化反应物料，因而有利于SiC晶须的生成；升温速度的控制可使SiC的生成速率与SiC晶须的生长速率得到很好的适应，此为提高SiC晶须产率的有效途径。
