Silicon Carbide e Nchafaditsweng (RXSIC, ReSIC, RSIC, R-SIC). Thepa e tala e qalang ke silicon carbide. Ha ho disebediswa tsa ho matlafatsa matla. Dikotwana tse tala di futhumatswa ho feta 2200ºC bakeng sa ho kopanya ha ho qetela. Thepa e hlahang e na le masoba a ka bang 25%, e leng se fokotsang thepa ya yona ya metjhini; leha ho le jwalo, thepa e ka ba hlwekile haholo. Tshebetso ena e theko e tlase haholo.
Karabelo e Kopantsoeng ea Silicon Carbide (RBSIC). Lisebelisoa tse tala tse qalang ke silicon carbide hammoho le carbon. Karolo e tala e kenngoa ka silicon e qhibilihisitsoeng ka holimo ho 1450ºC ka karabelo: SiC + C + Si -> SiC. Sebopeho sa microstructure ka kakaretso se na le silicon e ngata e feteletseng, e fokotsang thepa ea eona ea mocheso o phahameng le ho hanyetsa ho bola. Phetoho e nyane ea boholo e etsahala nakong ea ts'ebetso; leha ho le joalo, lera la silicon hangata le ba teng holim'a karolo ea ho qetela. ZPC RBSiC li amoheloa theknoloji e tsoetseng pele, e hlahisang lesela la ho hanyetsa ho bola, lipoleiti, lithaele, lesela la sefefo, li-block, likarolo tse sa tloaelehang, le li-nozzle tsa FGD tsa ho hanyetsa ho bola le ho bola, exchanger ea mocheso, liphaephe, li-tube, jj.
Nitride Bonded Silicon Carbide (NBSIC, NSIC). Lisebelisoa tse tala tse qalang ke silicon carbide hammoho le phofo ea silicon. Compact e tala e besoa moeeng oa naetrojene moo karabelo ea SiC + 3Si + 2N2 -> SiC + Si3N4 e etsahalang. Thepa ea ho qetela e bontša phetoho e nyane ea boholo nakong ea ts'ebetso. Thepa e bontša boemo bo itseng ba masoba (hangata hoo e ka bang 20%).
Silicon Carbide e Sintered ka ho Otloloha (SSIC). Silicon carbide ke thepa e tala e qalang. Dithuso tsa ho matlafatsa ke boron hammoho le khabone, mme ho matlafatsa ho etsahala ka tshebetso ya karabelo ya boemo bo tiileng ka hodimo ho 2200ºC. Dithoto tsa yona tsa mocheso o phahameng le ho hanyetsa mafome di phahame ka lebaka la ho hloka mohato wa bobedi o kang khalase meeding ya dijo-thollo.
Silicon Carbide e Sintered ea Motsoako oa Metsi (LSSIC). Silicon carbide ke thepa e tala ea ho qala. Lisebelisoa tsa ho eketsa matla ke yttrium oxide hammoho le aluminium oxide. Ho eketsa matla ho etsahala ka holimo ho 2100ºC ka karabelo ea mokelikeli 'me ho fella ka mokhahlelo oa bobeli o kang khalase. Litšobotsi tsa mechini ka kakaretso li phahametse SSIC, empa litšobotsi tsa mocheso o phahameng le ho hanyetsa mafome ha li ntle hakaalo.
Silicon Carbide e Hatelitsoeng ka Mocheso (HPSIC). Phofo ea silicon carbide e sebelisoa e le thepa e tala ea ho qala. Lisebelisoa tsa ho matlafatsa ka kakaretso ke boron hammoho le carbon kapa yttrium oxide hammoho le aluminium oxide. Ho matlafatsa ka matla ho etsahala ka ho sebelisoa ha khatello ea mechine le mocheso ka har'a cavity ea graphite die. Libopeho ke lipoleiti tse bonolo. Bongata bo tlase ba lisebelisoa tsa ho futhumatsa bo ka sebelisoa. Lisebelisoa tsa mechine tsa lisebelisoa tse hatelitsoeng ka matla li sebelisoa e le motheo oo lits'ebetso tse ling li bapisoang khahlanong le oona. Lisebelisoa tsa motlakase li ka fetoloa ke liphetoho tsa lisebelisoa tsa ho matlafatsa ka matla.
CVD Silicon Carbide (CVDSIC). Thepa ena e boptjoa ke ts'ebetso ea ho kenngoa ha mouoane oa lik'hemik'hale (CVD) e kenyeletsang karabelo: CH3SiCl3 -> SiC + 3HCl. Karabelo e etsoa tlas'a sepakapaka sa H2 moo SiC e kenngoeng holim'a substrate ea graphite. Ts'ebetso ena e fella ka thepa e hloekileng haholo; leha ho le joalo, ke lipoleiti tse bonolo feela tse ka etsoang. Ts'ebetso ena e theko e boima haholo ka lebaka la linako tse liehang tsa karabelo.
Khemikhale ea Mouoane oa Silicon Carbide (CVCSiC). Ts'ebetso ena e qala ka selelekela sa graphite se ikhethileng se entsoeng ka mechini ho etsa libopeho tse haufi le letlooa boemong ba graphite. Ts'ebetso ea phetoho e beha karolo ea graphite karabelong ea boemo bo tiileng ba mouoane ho hlahisa SiC e nang le polycrystalline, e nepahetseng ka mokhoa o sa fetoheng. Ts'ebetso ena e laoloang ka thata e lumella meralo e rarahaneng ho hlahisoa karolong ea SiC e fetotsoeng ka botlalo e nang le likarolo tsa mamello e tiileng le bohloeki bo phahameng. Ts'ebetso ea phetoho e khutsufatsa nako e tloaelehileng ea tlhahiso mme e fokotsa litšenyehelo ho feta mekhoa e meng.* Mohloli (ntle le moo ho boletsoeng teng): Ceradyne Inc., Costa Mesa, Calif.
