Abstract : The method involves the determination of the integral intensity of the spectra at a specified wavelength - 3.34A for quartz, 3.15A for cristobalite, and 3.81A for tridymite. The values for the integral intensities are obtained from the product of the line height and width at the half point of its height. Standard mixtures have been prepared from the three pure components, and eight samples have been analysed. Results are presented and discussed. (Author)
