X射线衍射定量相分析在确定绿鳞石矿物化学结构式中的应用

Application of Quantitative Phase Analysis by X-Ray Diffraction in Determining The Chemical Formula of Celadonite

通常,矿物的化学结构式是根据提取的纯标样的化学全分析资料来确定的。但是,由于种种原因,有时纯标样不易得到。本文探讨了在一定条件下,利用衍射定量分析技术对不纯标样的化学结构式进行确定,取得了较为满意的结果。我们在四川铜街子某工程基础下的软弱夹层中,发现有绿鳞石矿物。为此,对它作了比较系统的研究。

The chemical formula of a mineral is usually determined from the chemical complete analysis of the pure mineral,which is not always obtainable.A method for the determination of the formula of an impure mineral was suggested by the use of X-ray quantitative phase analysis.Satisfactory molecular formulas of celadonite have been calculated from the chemical data of several impure samples.
