铁矿石是重要的矿产资源,搞清楚其中各种铁矿物的含量,对于合理利用矿产资源具有一定的现实意义。这项工作通常采用化学物相分析法或X射线物相分析法,它们可以互相补充,互相验证。 X射线物相定量分析,自L.E亚历山大(Alexander)和H.P.克卢格(Klug)1948年提出后,至今已有了很大的发展。但是无论内标法、直接法、还是稀释法、参考强度 Iron ore is an important mineral resource. To find out the content of various iron minerals in it has certain practical significance for the rational utilization of mineral resources. This work is usually carried out using chemical phase analysis or X-ray phase analysis, they can complement each other to verify each other. Quantitative X-ray phase analysis has been greatly developed since L.E. Alexander and H.P. Klug were proposed in 1948. However, regardless of the internal standard method, the direct method, or dilution method, reference intensity
