摘要
利用粉晶X射线衍射分析方法,研究了海泡石在热处理过程中的相变特征。研究发现,海泡石在受热后将向滑石转变,并可分为4个阶段:室温~200℃,为海泡石相;300~700℃,为向滑石转化的过渡相;800~900℃,为混合相;900~1000℃,为顽火辉石相。
y the powder X ray diffraction analysis, the authors have studied the characteristics of the phase changing of sepiolite in the course of heat treatment. Sepiolite will change toward talc after heated. The phase changing can be divided into four stages: the sepiolite phase in temperature range of 25~200℃, a kind of interim phase to talc in range of 300~700℃, a mix phase in range of 800~900℃, the enstatite phase in range of 900~1000℃.
