Na Silicon Nitride e Turu?

(Na Silicon Nitride e Turu?)

Silicon nitride ke thepa e matla haholo, e thata haholo, e hananang le ho bola le ho roala. Ho tiea ha eona ka mochine ho boetse ho etsa hore e khone ho mamella mocheso o phahameng. E loketse libaka tse apereng haholo, joalo ka li-blade tsa turbine le li-shafts tse nepahetseng. E boetse e hanyetsana le litšepe tse se nang ferrous, e etsa hore e tšoanelehe bakeng sa lisebelisoa tse phahameng tsa mocheso.

Silicon nitride le eona ke bioinert, e e lumellang hore e sebelisoe bakeng sa li-implants tsa biomedical. Ho elella bofelong ba lilemo tsa bo-1980, bo-rasaense ba ile ba tiisa hore boitsebiso boo bo ne bo lumellana le lintho tse phelang ha bo kenngoa liphoofolong. Phuputso ea 1999 e netefalitse phumano ena, e bonts'a hore silicon nitride e na le biocompatible ka ho lekana bakeng sa phatlalatso ea in vitro ea lisele tsa masapo.

Ho na le mefuta e 'meli ea mantlha ea silicon nitride. Ea pele ke silicon nitride e hatelitsoeng ka ho chesa, e sebelisetsoang ho seha lisebelisoa. Mofuta oa bobeli, sintered reaction-bonded silicon nitride, e ntlafalitse ho hanyetsa le ho tiea. Sena se kenyelletsa ho tlama silicon nitride ho graphite ebe o sinter ka mocheso o phahameng kapa likhatello.

Silicon nitride ke thepa e ikemetseng e nang le matla a holimo a atomic a tlamahaneng. Ka lebaka leo, e hanyetsana haholo le kutu ka tharollo ea asiti le ea mantlha. Sena se etsa hore e be khetho e tsebahalang bakeng sa lits'ebetso tsa meralo liindastering tse fapaneng. Hape ke thepa e ntle haholo bakeng sa lisebelisoa tse sa tsitsang le tse nang le mocheso o phahameng.

Silicon nitride e phahame ka ho senya le ho hanyetsa mocheso oa mocheso ha o bapisoa le tšepe ea boemo bo phahameng. Silicon nitride e ka boela ea sebelisoa li-bearings hobane e bobebe ho feta tšepe. Boima ba eona bo tlase bo etsa hore e be bobebe joalo ka aluminium, e fokotsa khatello ea maikutlo merabeng ea kantle.

U ka etsa likarolo tse ngata tse fapaneng tsa meralo ho tloha silicon nitride. Precision Ceramics e boloka mefuta e mengata e fapaneng ea lithupa tsa ceramic tsa silicon nitride tse nang le pheletso e ntle ea bokaholimo. Lithupa tsena li loketse likarolo tsa enjene, lipiston, li-bearings le lits'ebetso tse ling. Khamphani e fana ka bokhoni bo felletseng ba ho sebetsa / ho sila ho hlahisa likarolo tsa silicon nitride.

Silicon nitride ke thepa ea maiketsetso ea ceramic ea maiketsetso. E sebetsana le naetrojene kapa metsoako e meng ea tlhaho e nang le li-silicon carriers le ammonia. E qalile ho sibolloa bohareng ba lekholo la bo18 la lilemo empa ho ne ho se bonolo ho e etsa ho fihlela hamorao. Hamorao, tlamahano e kopanetsoeng ea silicon le naetrojene e lebisitse ho nts'etsopele ea mefuta e 'meli ea mantlha ea silicon nitride: sintered silicon nitride le reaction-bonded silicon nitride.

Silicon nitride ke ceramic ea bohlokoa ea boenjiniere e sebelisoang lits'ebetsong tse ngata tse fapaneng. Ho sa tsotellehe mocheso oa eona o phahameng, e na le lisebelisoa tse ikhethang tsa mechine le lik'hemik'hale. Ke thepa e ntle haholo ea ho etsa li-capacitor ka li-chips tsa analog. Silicon nitride e boetse e sebelisoa lits'ebetsong tsa biomedical.

Botenya bo nepahetseng ba nitride bo itšetlehile ka pad le botenya ba oxide ea tšimo. Lera le letenya la nitride le eketsa khatello ea mochini ho silicon nakong ea oxidation ea tšimo. Haeba likhatello tsena li feta meeli e boima, li ka baka ho kheloha, ho lebisa ho liheke tsa transistor tse lutlang. Botenya bo nepahetseng ba lera la nitride e lokela ho ba lipakeng tsa 150 nm ho isa ho 200 nm. Ka nako e ts'oanang, botenya ba pad oxide bo lokela ho ba pakeng tsa 10 nm ho 20 nm.

Mabapi le RBOSCHCO

RBOSCHCO ke mofani le moetsi oa lik'hemik'hale ea tšepahalang lefatšeng ka bophara ea nang le boiphihlelo ba lilemo tse fetang 12 ho faneng ka lik'hemik'hale tsa boleng bo holimo le lintho tse ling tse kang Nanomaterials. Khamphani e romela linaheng tse ngata, tse kang USA, Canada, Europe, UAE, Afrika Boroa, Tanzania, Kenya, Egepeta, Nigeria, Cameroon, Uganda, Turkey, Mexico, Azerbaijan, Belgium, Cyprus, Czech Republic, Brazil, Chile, Argentina, Dubai, Japane, Korea, Vietnam, Thailand, Malaysia, Indonesia, Australia, Jeremane, Fora, Italy, Portugal jj. Jwalo ka moetsi ea etellang pele nts'etsopele ea nanotechnology, RBOSCHCO e laola 'maraka. Sehlopha sa rona sa mosebetsi sa litsebi se fana ka litharollo tse phethahetseng ho thusa ho ntlafatsa katleho ea liindasteri tse fapaneng, ho theha boleng, le ho sebetsana habonolo le liphephetso tse fapaneng.
