Silicon carbide e itšoara joaloka daemane. Ha se feela e bobebe ka ho fetesisa, empa hape ke thepa e thata ka ho fetisisa ea ceramic mme e na le conductivity e ntle ea mocheso, katoloso e tlase ea mocheso ebile e hanyetsana haholo le li-acid le li-lye.
Ka silicon carbide ceramics thepa ea thepa e lula e le teng ho fihlela mocheso o ka holimo ho 1,400 ° C. High Young's modulus> 400 GPa e netefatsa botsitso bo botle ba sebopeho. Lintho tsena tsa thepa li etsa hore silicon carbide e reriloe esale pele hore e sebelisoe e le thepa ea kaho. Silicon carbide masters corrosion, abrasion le khoholeho ea mobu ka boqhetseke joalo ka ha e emela moaparo oa likhohlano. Lisebelisoa li sebelisoa limela tsa lik'hemik'hale, limilone, li-extruder le li-extruder kapa e le li-nozzles, mohlala.
"Mefuta e fapaneng ea SSiC (sintered silicon carbide) le SiSiC (silicon infiltrated silicon carbide) e iketsetse. Ea morao-rao e loketse ka ho khetheha bakeng sa tlhahiso ea metsoako e rarahaneng ea molumo o moholo.”
Silicon carbide e bolokehile ka chefo ebile e ka sebelisoa indastering ea lijo. Ts'ebeliso e 'ngoe e tloaelehileng ea likarolo tsa silicon carbide ke theknoloji ea ho tiisa ka matla e sebelisang li-friction bearings le litiiso tsa mochini, mohlala lipompong le lits'ebetsong tsa koloi. Ha ho bapisoa le litšepe, silicon carbide e thusa litharollo tsa moruo haholo ka bophelo bo bolelele ba lisebelisoa ha li sebelisoa ka mecha ea litaba e mabifi, e phahameng haholo. Li-ceramics tsa silicon carbide le tsona li loketse ho sebelisoa maemong a boima ho ballistics, tlhahiso ea lik'hemik'hale, theknoloji ea matla, tlhahiso ea pampiri le likarolo tsa tsamaiso ea liphaephe.
Reaction bonded silicon carbide, eo hape e tsejoang e le siliconized silicon carbide kapa SiSiC, ke mofuta oa silicon carbide o hlahisoang ke karabelo ea lik'hemik'hale lipakeng tsa porous carbon kapa graphite e nang le silicon e qhibilihisitsoeng. Ka lebaka la mesaletsa e setseng ea silicon, reaction bonded silicon carbide hangata e bitsoa siliconized silicon carbide, kapa khutsufatso ea eona ea SiSiC.
Haeba silicon carbide e hloekileng e hlahisoa ke sintering ea silicon carbide powder, hangata e na le mesaletsa ea lik'hemik'hale tse bitsoang sintering aids, tse kenyelletsoang ho tšehetsa mokhoa oa ho sintering ka ho lumella mocheso o tlase oa sintering. Mofuta ona oa silicon carbide hangata o bitsoa sintered silicon carbide, kapa e khutsufatsoe ho SSiC.
silicon carbide phofo e fumanoa ho silicon carbide e hlahisoang joalokaha ho hlalositsoe sehloohong sa silicon carbide.
