Abstract

Freshly ground quartz and naturally occurring crystalline quartz found in ball clays were examined by x-ray diffraction (XRD) and diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) to obtain crystallinity of the quartz. In addition to semi-quantitative x-ray methods described by Murata and Norman (1976), a new diffuse reflectance infrared spectroscopy method is proposed to determine quartz crystallinity. The bands at 800 and 780 cm -1 were used to measure the crystallinity of quartz. It is showed that the band at 780 cm-1 is very sensitive to crystallinity of materials containing quartz. A correlation was observed between results from x-ray diffractometry and results from diffuse reflectance infrared Fourier transform spectroscopy.
