Silicon nitride ceramic e nang le thepa e ntle ea 'mele, ea lik'hemik'hale le ea mochini
Li-ceramics tsa silicon nitride li na le melemo e ikhethang: letsoalo le tlase, ho hanyetsa mocheso o phahameng, ho itšehla thajana, ho hanyetsa kutu. Dense Si3N4li-ceramics li boetse li bonts'a boima bo phahameng ba ho robeha, thepa e phahameng ea modulus le ho itšehla thajana, e ka ba ho hanyetsa ka mokhoa o babatsehang ho mefuta e fapaneng ea ho apara le ho mamella maemo a thata a ka etsang hore lisebelisoa tse ling tsa ceramic li phatlohe, li senyehe kapa li oe, ho akarelletsa le mocheso o feteletseng, phapang e khōlō ea mocheso; le vacuum e phahameng haholo.
Lisebelisoa tse ka Sehloohong tsa Silicon Nitride Ceramics
Boenjineri ba mechini: Li-ceramics tsa silicon nitride li na le boima bo phahameng, ho hanyetsa ho apara hantle le ho hanyetsa kutu, 'me li sebelisoa haholo masimong a boenjiniere ba mechini. E ka sebelisoa ho etsa likarolo tse kang li-bearings, litiiso, lisebelisoa tsa ho itšeha le li-nozzles ka mocheso o phahameng le lebelo, ho fana ka ts'ebetso e babatsehang le bophelo bo bolelele.
Indasteri ea likoloi: Ka lebaka la botsitso ba mocheso o phahameng le khanyetso ea ho roala ha silicon nitride ceramics, e sebelisoa ha ho etsoa likarolo tsa enjene ea likoloi. Li-ceramics tsa silicon nitride li ka sebelisoa ho etsa likarolo tsa enjine tse sebetsang hantle joalo ka mehele ea piston, li-cylinder liner le li-valve, ho thusa ho ntlafatsa ts'ebetso ea mafura le ho fokotsa mesi.
Sepakapaka: Boima bo bobebe, matla a phahameng le ho hanyetsa mocheso o phahameng oa li-ceramics tsa silicon nitride li li etsa lisebelisoa tse loketseng bakeng sa lisebelisoa tsa sefofane. E ka sebelisoa ho etsa likarolo tsa bohlokoa tse kang likarolo tsa enjene, li-blades tsa turbine, lisebelisoa tsa ho itšehla thajana le sepakapaka se sireletsang mocheso ho finyella litlhoko tsa mocheso o phahameng, khatello e phahameng le libaka tse feteletseng.
Indasteri ea lik'hemik'hale: Li-ceramics tsa silicon nitride li sebelisoa haholo indastering ea lik'hemik'hale ka lebaka la botsitso ba tsona ba lik'hemik'hale le ho hanyetsa kutu. Li-ceramics tsa silicon nitride li ka sebelisoa ho etsa likepe tsa lik'hemik'hale tsa lik'hemik'hale, li-catalyst carriers, lisebelisoa le liphaephe tse thibelang acid le alkali, 'me li ka mamella mecha ea litaba e senyang le maemo a phahameng a mocheso.
Optoelectronics: Li-ceramics tsa silicon nitride li na le thepa e ntle ea optical le ea elektroniki, ka hona li na le lits'ebetso tsa bohlokoa lefapheng la optoelectronics. E ka sebelisoa ho etsa mocheso o phahameng le matla a phahameng a fiber amplifiers, lasers, lisebelisoa tsa puisano tsa optical le optical Windows ... joalo-joalo, e nang le transmittance optical e babatsehang le botsitso ba mocheso.
