Siliconized graphite wani hadadden abu ne wanda silicon carbide ke haɗe zuwa saman faifan graphite.Yana da halaye na high taurin, high inji ƙarfi da juriya na silicon carbide, kazalika da kai lubricating Properties da thermal girgiza juriya na graphite.Yana da manufa gogayya kayan da inji hatimi kayan, dace da inji sealing na daban-daban ruwa famfo, man famfo, sinadarai farashinsa, da bearings na daban-daban high-gudun da high-load babban farashinsa.Bugu da kari, siliconized graphite yana da kyau juriya hadawan abu da iskar shaka juriya, thermal shock juriya, low porosity, da kuma wasu lantarki watsin, kuma za a iya amfani da matsayin kayan kamar karfe smelting crucibles da daftarin tube.
A abun da ke ciki na siliconizedgraphite ne uniform, da surface daidai da ciki, da kuma abun da ke ciki rabo na silicon carbide da graphite daidaitacce.Mafi girman abun ciki na siliki carbide, mafi girman nauyin kayan, mafi girman ƙarfin matsawa, kuma tsayayya yana ƙaruwa.
