Testing of ceramic raw and basic materials. Direct determination of mass fractions of impurities in powders and granules of silicon carbide by OES by DC arc excitation Ingestion-build-44680 Testing institutes1 Scope This European Standard describes the method for the analysis of mass fractions of the impurities Al, B, Ca, Cr, Cu, Fe, Mg, Ni, Ti, V and Zr in powder and grain shaped silicon carbide of ceramic raw and basic materials. This application can also be extended to other metallic elements and other similar non metallic powder and grain shaped materials such as carbides, nitrides, graphite, carbon blacks, cokes, carbon, as well as a number of
