Garaafka silikoonized waa walxo isku dhafan oo silikoon carbide ku xiran tahay dusha sare ee garaafyada.Waxay leedahay sifooyinka qallafsanaanta sare, xoogga farsamada sare iyo xidhashada caabbinta ee carbide silicon, iyo sidoo kale sifooyinka is-saliid iyo caabbinta shoogga kulaylka ee graphite.Waa qalab isku-dhafan oo ku habboon iyo qalabka shaabadda makaanikada, oo ku habboon xiridda makaanikada ee matoorada biyaha ee kala duwan, bambooyinka saliidda, bambooyin kiimikaad, iyo xajiyeyaasha kala duwan ee xawaaraha sare iyo kuwa xamuulka ah ee bambooyin waaweyn oo kala duwan.Intaa waxaa dheer, graphite siliconized wuxuu leeyahay iska caabin oksaydh oo wanaagsan, caabbinta shoogga kulaylka, porosity hooseeya, iyo korantada korantada qaarkood, waxaana loo isticmaali karaa agabka sida birta dhalaalaysa iyo tuubooyinka qabyada ah.
Halabuurka siliconizedgraphite waa lebis, dusha sare waa la socda gudaha, iyo saamiga ka kooban ee carbide silicon iyo graphite waa hagaajin.Maaddaama ay ka sii badan tahay maadada silikoon carbide, cufnaanta maaddadu way sii badanaysaa, way sii badanaysaa xoogga cufan, adkaysiguna wuu kordhaa.
