摘要
本文讨论了用TG方法对滑石进行物相定量分析的结果。实验证明其分析精度完全可以满足地质上评价滑石矿床的要求。滑石在加热过程中,于930℃失去羟基,根据失去羟基的量值对滑石进行物相定量分析。该方法可以排除其它硅酸盐矿物对分析结果的干扰,制样方便,所需样品量小,样品不需特殊处理,分析误差±3%。
This paper studies the result of quantitative phase analysis of tale with TG method.This experiment is proved that the precision is better,therefore this method can satisfy geological requirment of evaluated talc deposit completely. On the course of heating,the talc will be losed hydroxyl at 930℃ nearby.Accor- ding to the value of losed hydroxyl,the content of talc is measured,obtained result is satisfactory.The erro is ±3%.
