methods of quantitative analysis of crystalline powder mixtures using x-ray diffraction (xrd) techniques are fairly well developed the analysis is relatively easy if the xrd pattern of the mixture exhibits component lines which do not overlap. in the reported study, a method has been developed to estimate the composition of a powder mixture using breadths of overlapping x-ray diffraction (xrd) lines. the application of the method is illustrated for analyzing blends of cotton and jute. it is concluded that quantitative analysis using breadths of x-ray diffraction lines may particularly suit semicrystalline polymeric materials which are characterized by relatively broad diffraction profiles. in cases of blends for which the analytical x-ray lines of the components do not overlap, the equations used for analysis will have to be modified by incorporating the difference in peak positions into the equations. 4 refs
