灰岩中的游离二氧化硅的化学物相分析方法的探讨

摘要

介绍了灰岩中游离二氧化硅的化学物相分析方法,以热浓磷酸溶矿,氟硼酸解聚已溶出的硅酸,使游离二氧化硅与其他矿物分离,再用重量法进行测定。%Introduced the chemistry phase analytic method of the dissociation silicon dioxide in calcareous rock,dissolved the dissociation silicon dioxide and other ore mineral by the heat thick phosphoric acid and the fluoboric acid depolymerization silicic acid which was dissolved,and used the weight method to carry on the determination again.
