Abstract:   (5568 Views)
This new method which is worked out in Isfahan University of Technology, makes it possible to analyze the phases quantitatively in minerals and powdered materials by X Ray Diffraction and without any reference material. To identify n unknown phases, n different combinations of phases, from fine and coarse fractions, or etc., must be obtained. Amorphous phases should not exist. Intensity ratios of selected peaks of different phases to the suitable peak of added substances are plotted against the weight ratio of unknown material to substances. The phase is used to eliminate the effect of absorption in measurements. After detecting the slopes of linear plots which pass through the origin, n equations are obtained which are solved for n unknown coefficients. The quantitative phase analysis is subsequently performed in all n samples. If reference materials are available for some phases, n is reduced. The method is to analyze three phases MgO, CaO, Ca(OH)2 with substance CaF2, in magnesite – dolomite, partially hydrated refractories.
