Silicon carbide tsarin

Manyan nau'ikan silicon carbide polymorph guda uku

Akwai kusan nau'ikan crystalline 250 na silicon carbide. Saboda silicon Carbide yana da jerin abubuwan polytypes tare da irin wannan tsarin kristal, silicon carbide yana da halayen da ke tattare da juna.

Silicon carbide (Mosanite) ba kasafai ba ne a duniya, amma yana da yawa a sararin samaniya. Cosmic silicon carbide yawanci abu ne na gama gari na ƙurar ƙura a kewayen taurarin carbon. Silikon carbide da aka samu a sararin samaniya da meteorites kusan ba ya canzawa β-lokaci crystalline.

A-sic shine mafi yawan waɗannan nau'ikan nau'ikan nau'ikan nau'ikan iri. An kafa shi a yanayin zafi sama da 1700 ° C kuma yana da tsari mai siffar crystal hexagonal kama da wurtzite.

B-sic, wanda ke da tsarin lu'u-lu'u kamar sphalerite, an kafa shi a ƙasa da 1700 ° C.
