Phase quantitative analysis of residual quartz in silica bricks — X-ray diffraction method

Description

This document specifies a method for the quantitative analysis of residual quartz (i.e. alpha-quartz) in silica bricks within the mass fraction range of 0,3 % to 5,0 %, by X-ray diffraction (XRD) using a Bragg-Brentano diffractometer. This document includes details of sample preparation and of preliminary establishment of a working curve using external standards.

This document does not address the safety issues associated with its use. The ground silica brick powders and reference materials may cause damage to lungs through prolonged or repeat inhalation during tests. It is responsibility of the users of this standard to establish appropriate safety and health practices.
