Menene rufin silicon carbide?

Rufin silicon carbide,wanda aka fi sani da SiC shafi, yana nufin tsarin shafa wani Layer na silicon carbide a saman ta hanyoyi kamar Chemical Vapor Deposition (CVD), Physical Vapor Deposition (PVD), ko fesawa mai zafi. Wannan murfin yumbu na silicon carbide yana haɓaka halayen saman abubuwa daban-daban ta hanyar ba da juriya ga lalacewa, kwanciyar hankali na zafi, da kariyar tsatsa. An san SiC saboda kyawun halayensa na zahiri da sinadarai, gami da babban wurin narkewa (kimanin 2700℃), tauri mai yawa (Mohs sikelin 9), kyakkyawan juriya ga tsatsa da iskar shaka, da kuma aikin kawar da gubobi.

Muhimman Fa'idodin Rufin Silicon Carbide a Aikace-aikacen Masana'antu

Saboda waɗannan fasalulluka, ana amfani da murfin silicon carbide sosai a fannoni kamar sararin samaniya, kayan aikin makamai, da sarrafa semiconductor. A cikin mawuyacin yanayi, musamman a cikin kewayon 1800-2000℃, murfin SiC yana nuna kwanciyar hankali mai ban mamaki da juriya ga abrative, wanda hakan ya sa ya dace da aikace-aikacen zafi mai yawa. Duk da haka, silicon carbide kaɗai ba shi da ingancin tsarin da ake buƙata don aikace-aikace da yawa, don haka ana amfani da hanyoyin rufewa don amfani da kaddarorinsa na musamman ba tare da rage ƙarfin sassan ba.
