In mineralogy, the carbide is known as cohenite (Fe,Ni,Co) 3 C, after the German mineralogist Emil Cohen, who was investigating material of meteoric origin. The impact of carbon-containing meteorites with the moon, is speculated to lead to a reduction of the iron-containing minerals on its surface; the resulting reaction with the carbonaceous gases generated by the impact to produce cementite

Abstract: Selective epitaxial growth (SEG) of cubic silicon carbide (3C-SiC) was carried out on patterned Si (100) substrates using SiO2 as a mask. The growth was performed by atmospheric pressure chemical vapour deposition in a resistance-heated furnace using hexamethyldisilane (HMDS) as …
2019/7/30· For XRD, the specimens were ground to powder using a ball mill with tungsten carbide (WC) as milling media. In the case of SiC p /Si composites, where the diffraction peaks of the β-SiC phase are coincidental with some diffraction peaks of the α-SiC phase, XRD does not allow for characterization of the reaction product.
