Silicon carbide e sebetsa jwalo ka daemane. Hase feela hore ke e bobebe ka ho fetisisa, empa hape ke thepa e thata ka ho fetisisa ya ceramic mme e na le motlakase o motle haholo, e na le katoloso e tlase ya mocheso mme e hanela haholo di-acid le di-lye.
Ka di-ceramic tsa silicon carbide, thepa ya thepa e dula e tsitsitse ho fihlela mochesong o ka hodimo ho 1,400°C. Modulus e phahameng ya Young e > 400 GPa e netefatsa botsitso bo botle ba tekanyo. Thepa ena ya thepa e etsa hore silicon carbide e rerelwe esale pele hore e sebediswe e le thepa ya kaho. Silicon carbide e hlola mafome, ho kgohlana le kgoholeho ya mobu ka boqhetseke jwalo ka ha e mamella tshenyo ya ho kgohlana. Dikarolo di sebediswa dimeleng tsa dikhemikhale, difekthering, di-extruder le di-extruder kapa jwalo ka di-nozzle, mohlala.
"Mefuta ea SSiC (sintered silicon carbide) le SiSiC (silicon infiltrated silicon carbide) e se e ikentse. Ea morao-rao e loketse haholo tlhahiso ea likarolo tse rarahaneng tsa boholo bo boholo."
Carbide ea silicon e bolokehile ka chefo 'me e ka sebelisoa indastering ea lijo. Tšebeliso e 'ngoe e tloaelehileng bakeng sa likarolo tsa carbide ea silicon ke theknoloji ea ho tiisa e matla e sebelisang li-friction bearing le litiiso tsa mechini, mohlala lipompong le litsamaisong tsa ho khanna. Ha e bapisoa le litšepe, carbide ea silicon e nolofalletsa litharollo tse theko e tlaase haholo tse nang le bophelo bo bolelele ba lisebelisoa ha li sebelisoa ka mecha ea phatlalatso e mabifi, e nang le mocheso o phahameng. Li-ceramic tsa carbide tsa silicon le tsona li loketse ho sebelisoa maemong a thata ho li-ballistics, tlhahiso ea lik'hemik'hale, theknoloji ea matla, tlhahiso ea pampiri le likarolo tsa sistimi ea liphaephe.
Carbide ea silicon e kopantsoeng le karabelo, e tsejoang hape e le carbide ea silicon e kopantsoeng le silicon kapa SiSiC, ke mofuta oa carbide ea silicon e hlahisoang ke karabelo ea lik'hemik'hale pakeng tsa khabone e nang le masoba kapa graphite ka silicon e qhibilihisitsoeng. Ka lebaka la mesaletsa e setseng ea silicon, carbide ea silicon e kopantsoeng le karabelo hangata e bitsoa carbide ea silicon e kopantsoeng le silicon, kapa khutsufatso ea eona SiSiC.
Haeba silicon carbide e hlwekileng e hlahiswa ka ho sila phofo ya silicon carbide, hangata e na le mesaletsa ya dikhemikhale tse bitswang di-sintering aids, tse eketswang ho tshehetsa tshebetso ya sintering ka ho dumella mocheso o tlase wa sintering. Mofuta ona wa silicon carbide hangata o bitswa silicon carbide e sintered, kapa o kgutsufatswa ho SSiC.
Phofo ea silicon carbide e fumanoa ho tsoa ho silicon carbide e hlahisoang joalo ka ha ho hlalositsoe sehloohong sa silicon carbide.
