Ụdị atọ bụ isi nke silicon carbide polymorph
Enwere ihe dị ka ụdị 250 nke kristal silicon carbide. N'ihi na silicon carbide nwere ọtụtụ ụdị polytypes nwere ụdị kristal yiri ya, silicon carbide nwere njirimara nke polycrystalline.
Silicon carbide (Mosanite) dị ụkọ n'ụwa, mana ọ na-adịkarị na mbara igwe. Cosmic silicon carbide na-abụkarị akụkụ a na-ahụkarị nke uzuzu ikuku gburugburu kpakpando carbon. Carbide silicon nke achọtara na mbara igwe na meteorites fọrọ nke nta ka ọ bụrụ kristal β-phase mgbe niile.
A-sic bụ ihe a na-ahụkarị na ụdị polytype ndị a. Emebere ya na okpomoku kariri 1700 Celsius ma nwee ihe owuwu kristal hexagonal yiri wurtzite.
B-sic, nke nwere ihe owuwu kristal sphalerite nke diamond, ka emebere na ihe na-erughị 1700C.
