BS EN 12698-2 is a European Standard that describes methods for the determination of mineralogical phases. These phases are typically apparent in nitride and oxy-nitride bonded silicon carbide refractory products using a Bragg-Brentano diffractometer.
BS EN 12698-2 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 under BS EN 12698-2.
Note: For the refinement procedures the total nitrogen content, analysis with BS EN 12698-1 is needed.
BS EN 12698-2 on XRD methods for chemical analysis of nitride bonded silicon carbide refractories is useful for:
Refractories are highly in demand for their various properties making them useful in various industries. Nitride bonded silicon carbide refractories have high thermal conductivity, superior thermal shock and oxidation resistance. They improve the thermal conductivity and enable rapid cooling.
BS EN 12698-2 assists in ensuring credibility as well as the optimum performance of the refractories through the XRD methods.
BS EN 12698-2 also guides you regarding the sampling preparation, measuring parameters, qualitative analysis and quantitative analysis for analysing nitride bonded silicon carbide refractories using XRD methods.
