Silicon carbide appears in two different crystalline forms: hexagonal α-silicon carbide is the main product, while cubic β-silicon carbide is formed at lower temperatures (Føreland et al., 2008). Silicon carbide occurs in several forms: as “non-fibrous,” as “polycrystalline fibres,” or as one of more than 150 different single-crystal modifiions (or polytypes) of “whiskers
