Chemical analysis of raw materials and refractory products containing silicon carbide, silicon nitride, silicon oxynitride and sialon - Part 4: XRD methods (ISO/FDIS 21068-4:2024); German version FprEN 21068-4:2024
Abstract
This document describes methods for the determination of mineralogical phases typically apparent in nitride and oxy-nitride bonded silicon carbide refractory products using a Bragg-Brentano diffractometer. It includes details of sample preparation and general principles for qualitative and quantitative analysis of mineralogical phase composition.
