Annotation of standard text ČSN EN ISO 21068-4 (726076):
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
