Chemical analysis of nitride bonded silicon carbide refractories - Part 2: XRD methods

This standard 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. Quantitative determination of -Si3N4, -Si3N4, Si2ON2, AlN, and SiAlON are described.
NOTE   For the refinement procedures the total nitrogen content, analysed in accordance with EN 12698-1 is needed.

Analyse chimique des produits réfractaires contenant du carbure de silicium lié au nitrure - Partie 2 : Méthodes de DRX

La présente norme 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 -Si3N4, -Si3N4, Si2ON2, AlN et SiAlON est décrite.
NOTE   Pour les modes opératoires d’affinement, il est nécessaire de connaître la teneur en azote total, analysée conformément au EN 12698-1.
