Chemical analysis of raw materials and refractory products containing silicon-carbide, silicon-nitride, silicon-oxynitride and sialon — Part 4: XRD methods

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 α-Si3N4, β-Si3N4, Si2ON2, AlN, and β’- SiAlON are described. For quantitative determination of α-Si3N4, β-Si3N4, Si2ON2, AlN and β’-SiAlON refinement procedures based on the total nitrogen content of the sample are described. NOTE ISO 21068-3 is used for the analysis of the total nitrogen content of the sample.

Analyse chimique des matières premières et des produits réfractaires contenant du carbure de silicium, du nitrure de silicium, de l’oxynitrure de silicium et du SiAlON — Partie 4: Méthodes de DRX

Le présent document décrit des méthodes destinées à déterminer les phases minéralogiques généralement présentes dans les produits réfractaires contenant du carbure de silicium lié au nitrure et à l’oxynitrure, au moyen d’un diffractomètre à géométrie Bragg-Brentano. Elle contient des détails relatifs à la préparation des échantillons ainsi que des principes généraux de l’analyse qualitative et quantitative de la composition des phases minéralogiques. La détermination quantitative de α-Si3N4, β-Si3N4, Si2ON2, AlN et β’-SiAlON est décrite. Concernant la détermination quantitative de α-Si3N4, β-Si3N4, Si2ON2, AlN et β’-SiAlON, des modes opératoire d’affinement basés sur la teneur en azote total de l’échantillon sont décrites. NOTE L'ISO 21068-3 est utilisée pour l'analyse de la teneur en azote total de l'échantillon.
