Measurements have been made on the composition, surface state, and morphology for green technical silicon carbide powders M28P, M7P, and M1N. The contents of the α-SiC 6H, β-SiC, and α-SiC 15R are identical for all the specimens. Measurements have been made on the amounts of the impurity phase iron silicide, graphite, and iron oxides, as well as silicon dioxide, which occur on the surfaces as an x-ray amorphous film of about 10 nm thickness. The SiC particles are mainly of platy form. The mean-number ratios of the length to width of the plates in projection are about 2, while the mean ratio of the thickness of the plates to the effective diameter is about 0.5.
