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

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. Il 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-a, Si3N4-v, Si20N2, AIN et SiAlON est décrite.

To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.
