Tsarin silicon carbide

Manyan nau'ikan polymorph guda uku na silicon carbide

Akwai nau'ikan silsila guda 250 na silicon carbide. Saboda silicon carbide yana da jerin nau'ikan silsila iri ɗaya masu kama da juna tare da tsarin lu'ulu'u iri ɗaya, silicon carbide yana da halaye na polycrystalline iri ɗaya.

Silicon carbide (Mosanite) ba kasafai yake samuwa a Duniya ba, amma yana da yawa a sararin samaniya. Cosmic silicon carbide yawanci wani abu ne da aka saba gani a cikin ƙurar sararin samaniya da ke kewaye da taurarin carbon. Silicon carbide da ake samu a sararin samaniya da meteorites kusan koyaushe yana kama da crystalline β-phase.

A-sic shine mafi yawan waɗannan nau'ikan polytypes. Ana samar da shi a yanayin zafi sama da 1700°C kuma yana da tsarin lu'ulu'u mai siffar hexagonal kamar wurtzite.

B-sic, wanda ke da tsarin lu'ulu'u mai kama da lu'ulu'u, yana samuwa a ƙasa da digiri 1700 na Celsius.
