Isakhiwo se-silicon carbide

Izinhlobo ezintathu eziyinhloko ze-silicon carbide polymorph

Kunezinhlobo ezingaba ngu-250 ze-silicon carbide ezikristalu. Ngenxa yokuthi i-silicon carbide inochungechunge lwama-polytype afanayo anesakhiwo sekristalu esifanayo, i-silicon carbide inezici ze-polycrystalline efanayo.

I-silicon carbide (i-Mosanite) ayivamile kakhulu eMhlabeni, kodwa ivame kakhulu emkhathini. I-cosmic silicon carbide ivame ukuba yingxenye evamile yothuli lwe-cosmic oluzungeze izinkanyezi ze-carbon. I-silicon carbide etholakala emkhathini nasema-meteorite cishe i-crystalline ye-β-phase.

I-A-sic iyona evame kakhulu kulezi polytypes. Yakhiwa emazingeni okushisa angaphezu kuka-1700°C futhi inesakhiwo sekristalu esinama-hexagonal esifana ne-wurtzite.

I-B-sic, enesakhiwo sekristalu se-sphalerite esifana nedayimane, yakhiwa ngaphansi kuka-1700°C.
