Matatu makuru marudzi esilicon carbide polymorph
Kune anenge mazana maviri nemakumi mashanu emhando dzecrystalline yesilicon carbide. Nekuti silicon carbide ine nhevedzano yehomogeneous polytypes ine yakafanana crystal chimiro, silicon carbide ine hunhu hwehomogeneous polycrystalline.
Silicon carbide (Mosanite) haiwanike paPasi, asi yakajairika muchadenga. Cosmic silicon carbide inowanzova chinhu chakajairika cheguruva recosmic rakatenderedza kabhoni nyeredzi. Iyo silicon carbide inowanikwa muchadenga uye meteorites inenge isingachinjiki β-phase crystalline.
A-sic ndiyo yakajairika pane idzi polytypes. Inoumbwa pakudziya kukuru kupfuura 1700 ° C uye ine hexagonal crystal chimiro chakafanana newurtzite.
B-sic, iyo ine dhaimondi-yakaita sesphalerite crystal chimiro, inoumbwa iri pasi pe1700 ° C.
