Isakhiwo se-silicon carbide

Izinhlobo ezintathu eziyinhloko ze-silicon carbide polymorph

Kunezinhlobo ezingaba ngu-250 ze-crystalline ze-silicon carbide. Ngenxa yokuthi i-silicon carbide inochungechunge lwama-polytypes ane-homogeneous ene-crystal structure, i-silicon carbide inezici ze-polycrystalline e-homogeneous.

I-silicon carbide (i-Mosanite) iyivelakancane kakhulu emhlabeni, kodwa ivame kakhulu emkhathini. I-cosmic silicon carbide ivamise ukuba yingxenye evamile yothuli lwe-cosmic ezungeze izinkanyezi ze-carbon. I-silicon carbide etholakala emkhathini kanye nama-meteorite cishe ngokungaguquguquki i-β-phase crystalline.

I-A-sic ivame kakhulu kulawa ma-polytypes. Yakheka emazingeni okushisa angaphezu kuka-1700 ° C futhi inesakhiwo sekristalu esiyi-hexagonal esifana ne-wurtzite.

I-B-sic, ene-diamond-like sphalerite crystal structure, yakhiwe ngaphansi kuka-1700°C.
