Tšebeliso e kholo ea Silicon Carbide

Silicon carbide e ntšo e entsoe ka lehlabathe la quartz le petroleum coke silica e le lisebelisoa tsa mantlha ka ho qhibiliha ha mocheso o phahameng ka sebōping sa ho hanyetsa. Boima ba eona bo pakeng tsa corundum le daemane, matla a eona a mochine a phahame ho feta corundum, 'me e brittle ebile e bohale. Silicon carbide e tala e entsoe ka petroleum coke le silica e le lisebelisoa tse ka sehloohong tse tala, tse nang le letsoai le ekelitsoeng e le motsoako, 'me li qhibilihisoa ka mocheso o phahameng ka sebōping sa ho hanyetsa. Boima ba eona bo pakeng tsa corundum le daemane, 'me matla a eona a mochine a phahame ho feta corundum.

Joale lisebelisoa tsa mantlha tsa silicon carbide ke life?
1. Li-Abrasives - Haholo hobane silicon carbide e na le boima bo phahameng, botsitso ba lik'hemik'hale le boima bo itseng, silicon carbide e ka sebelisoa ho etsa li-abrasives tse kopantsoeng, li-abrasive tse koahetsoeng le ho sila mahala bakeng sa ho sebetsa likhalase le lirafshoa. , lejoe, tšepe e entsoeng ka tšepe le lisebelisoa tse ling tse se nang ferrous, carbide, alloy ea titanium, lisebelisoa tsa ho itšeha ka lebelo le phahameng le mabili a silang, joalo-joalo.

2. Lisebelisoa tse hanyetsanang le lisebelisoa tse thibelang ho bola --- Haholo hobane silicon carbide e na le ntlha e phahameng ea ho qhibiliha (tekanyo ea ho bola), inertness ea lik'hemik'hale le ho hanyetsa mocheso oa mocheso, silicon carbide e ka sebelisoa ka li-abrasives le lisebelisoa tsa ho chesa lihlahisoa tsa ceramic. Lipoleiti tse tšolotsoeng le li-sagger, litene tsa silicon carbide bakeng sa libono tse otlolohileng tsa cylinder distillation indastering ea smelting ea zinki, aluminium electrolytic cell linings, crucibles, lisebelisoa tse nyane tsa sebōpi le lihlahisoa tse ling tsa silicon carbide ceramic.

3. Tšebeliso ea lik'hemik'hale-hobane silicon carbide e ka bola ka tšepe e qhibilihisitsoeng 'me ea itšoara ka oksijene le li-oxide tsa tšepe ka har'a tšepe e qhibilihisitsoeng ho hlahisa carbon monoxide le slag e nang le silicon. Ka hona, e ka sebelisoa e le sesebelisoa sa ho hloekisa bakeng sa tšepe e qhibilihisang, ke hore, e le deoxidizer le lisebelisoa tse ntlafatsang tsa tšepe bakeng sa ho etsa tšepe. Sena ka kakaretso se sebelisa bohloeki bo tlase ba silicon carbide ho fokotsa litšenyehelo. E ka boela ea sebelisoa e le thepa e tala bakeng sa ho etsa silicon tetrachloride.

4. Lisebelisoa tsa motlakase - tse sebelisoang e le lisebelisoa tsa ho futhumatsa, lisebelisoa tse sa tsitsang le lisebelisoa tse phahameng tsa semiconductor. Lintho tse futhumatsang tse kang lithupa tsa silicon carbon (tse loketseng libōpi tse fapaneng tsa motlakase tse sebetsang ho 1100 ho isa ho 1500 ° C), lisebelisoa tse sa tsitsang le li-valve tse fapaneng tse sireletsang lehalima.
