About This Item

 

Full Description

DRAFT

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 α-Si3N4, β-Si3N4, Si2ON2, AlN, and SiAlON are described. NOTE – For the refinement procedures the total nitrogen content, analysed in accordance with ISO 21068-3 is needed.
