摘要
本文通过SEM、XRD、DTA、FT IR等测试手段对高岭土和氢氧化铝的高能球磨过程进行了研究。结果表明 ,高能球磨可以使该混合物发生明显的机械力化学变化 ,粉磨后颗粒形貌改变 ,粒径变小 ,晶体变成无定形态 ,部分化学键出现断裂。
The process of grinding a kaolinite and aluminum trihydroxide mixture using a high energy ball mill was investigated by SEM,XRD,DTA and FT-IR.The results showed that high energy milling led to obvious mechanochemical changes of mixture.After ground,particles losed their original shapes,the paticle size reducted,crystal transferred into amporphous and partial chemical bonds breaked.The analysis provides the theoretical foundation for formation of mullite at low temperature.
