CaO杂质在莫来石-高硅氧玻璃材料中的分布
Distribution of CaO impurity in mullite-silica-rich glass material
【摘要】 对M40莫来石-高硅氧玻璃复合材料的杂质及CaO分布进行了分析,发现K2O、Na2O、MgO、Fe2O3和TiO2杂质的大部分进入了玻璃相中,但CaO却以CaSiO3的形式呈点状集中分布于晶相中,HF酸不能将其溶解,而是与其反应生成CaF2。
【Abstract】 The distribution of impurities and CaO in M40 mullite-silica-rich glass composite was analyzed.A majority of impurities such as K2O,Na2O,MgO,Fe2O3 and TiO2 were found dissolved in glass-phase.However CaO was found concentrated and spotted in the crystalline phase in form of CaSiO3,which could not be dissolved by HF acid,but reacted with HF into CaF2.
