Quantitative determination of mineral composition by powder X-ray diffraction
Abstract
An external standard intensity ratio method is used for quantitatively determining mineralogic compositions of samples by X-ray diffraction. The method uses ratios of X-ray intensity peaks from a single run. Constants are previously determined for each mineral which is to be quantitatively measured. Ratios of the highest intensity peak of each mineral to be quantified in the sample and the highest intensity peak of a reference mineral contained in the sample are used to calculate sample composition.
