DESCRIPTION

CSN EN ISO 21068-4

CSN EN ISO 21068-4 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 preparations and general principles for qualitative and quantitative analyses of mineralogical phase composition. Quantitative determination of alpha-Si3N4, ß-Si3N4, Si2ON2, AlN, and ß'- SiAlON are described. For quantitative determination of alpha-Si3N4, ß-Si3N4, Si2ON2, AlN and ß'-SiAlON refinement procedures based on the total nitrogen content of the sample are described.
