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 (Swedish Standard) 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
Comparison of sample preparation methods for …
Several sample preparation methods were evaluated for determination of free carbon in boron carbide powders by quantitative X-ray diffraction method, including ultrasoniion, wet ball milling and dry ball milling–wet mixing. Quantitation was based on measuring the integral peak area ratio of the diffraction lines of graphite (002) to boron carbide (012) in samples spiked with pure graphite
Silicon Carbide | Definition of Silicon Carbide by …
Silicon carbide definition is - a very hard dark crystalline compound SiC of silicon and carbon that is used as an abrasive and as a refractory and in electric resistors. Recent Examples on the Web These beads, each only a millimeter in diameter and the consistency of a jelly bean, are then put in a furnace that is injected with gases that break down in the oven, depositing thin layers of
