Abstract

Due to the classification of crystalline silica ns a human carcinogen, health regulations necessitate the determination of α-quartz in respirable dust and bulk materials in the industrial environment, A variety of analytical methods, including X-ray diffraction and infrared spectroscopy (IR), have been used to determine crystallinity degree of quartz in bulk materials. In addition to determination of crystalline silica in respirable dust, Murata and Norman (1976) proposed a semi-quantitative XRD method for measuring quartz crystallinity in bulk materials as well as minerals. The determination of full-with-at-half-maximum (FWHM) for quartz diffraction line in sample such as clay, coal and cement containing quartz an accessory mineral can be used to evaluate Murata's crystallinity index for the quartz. The measurement of FWHM for quartz in bulk materials will accelerate practically the determination of crystallinity of quartz.
