| 摘 要： | 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。 |

| Abstract: | the authors did the systematical researches on the interactions of muscovite and different alkaline agents with various concentrations. Liquid and solid parameters were detected, respectively. Results for muscovite in alkalis show there exist instant dissolution trend and vibrating trend during the process.Difference in concentration of NaOH causes much more difference in dissolution extent than that of NaCO3 does. Silicon/aluminum ratio in reaction solution is equal to that in primary solid, which indicates consistent dissolution occurs. Temperature rise can enhance the dissolution of muscovite in alkalis. |
