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

Silicon carbide, image taken under a stereoscopic microscope. Silicon carbide exists in about 250 crystalline forms. [31] Through the inert atmosphere pyrolysis of preceramic polymers, silicon carbide in a glassy amorphous form is also produced. [32] The polymorphism of SiC is characterized by a large family of similar crystalline structures called polytypes.
