Ọdịdị silicon carbide

Ụdị isi atọ nke silicon carbide polymorph

E nwere ihe dị ka ụdị kristal 250 nke silicon carbide. Ebe ọ bụ na silicon carbide nwere usoro polytypes yiri nke ahụ nwere nhazi kristal yiri nke ahụ, silicon carbide nwere njirimara nke polycrystalline yiri nke ahụ.

A naghị ahụkarị silicon carbide (Mosanite) n'ụwa, mana ọ na-adịkarị na mbara igwe. Cosmic silicon carbide na-abụkarị ihe a na-ahụkarị na uzuzu mbara igwe gburugburu kpakpando carbon. Silicon carbide a na-ahụ na mbara igwe na meteorites fọrọ nke nta ka ọ bụrụ kristal β-phase mgbe niile.

A-sic bụ ụdị polytype ndị a kacha ahụkarị. A na-akpụ ya n'okpomọkụ karịrị 1700°C ma nwee nhazi kristal hexagonal yiri wurtzite.

A na-emepụta B-sic, nke nwere nhazi kristal sphalerite dị ka dayamọnd, na obere okpomọkụ erughị 1700°C.
