摘要
用不同种烟煤与SiO2 为原料在氮气保护下低温合成 β -SiC产率相差很大。本文在与合成SiC相同的温度和气氛条件下对各种烟煤的焦炭进行了X -射线衍射分析 ,计算了其微晶结构参数 ,探讨了各种烟煤微晶结构特点、活性及其对SiC合成的影响。
Different soft coal was investigated in β-SiC low temperature synthetic reaction.There is a significant difference of SiC productivity due to different soft coal.Under the same temperature and atmosphere as SiC synthetic reaction,various soft coal coke was studied by X-Ray.The micro-crystalline parameter was calculated.Relationship between micro crystalline structure character and activity and SiC synthesis was discussed in detail.
