系统地研究了白云母与碱剂（Ｎａ２ＣＯ３和ＮａＯＨ）间的相互作用；分别对反应后的液相参数和固相参数进行了全面测定。研究结果表明：白云母在碱剂中存在短期瞬时效应和振荡变化趋势；ＮａＯＨ浓度差异对白云母溶蚀程度的影响明显强于Ｎａ２ＣＯ３浓度差异对它的影响。此外，反应液中硅铝元素浓度之比与原始固相中的比例一致说明白云母在碱剂中发生了一致性溶蚀；而温度升高可以促进白云母的溶蚀
The interaction between muscovite and alkali agent (Na2CO3 and NaOH) was studied systematically. The liquid phase parameters and solid phase parameters were determined after the reaction. The results show that there is a short-term transient effect and oscillatory trend of muscovite in alkaline agent. The effect of NaOH concentration on muscovite dissolution is obviously stronger than that of Na2CO3 concentration. In addition, the ratio of the concentrations of Si and Al in the reaction liquid to those in the original solid phase indicates that consistent dissolution of muscovite occurs in the alkali agent; and the increase of temperature can promote the dissolution of muscovite
