Silicon e Carbide SIC
1.Product e qaqileng
K'habone e ntšo ea kristale ea silicone e nang le letsoalo le phahameng e hlahisoang semeleng sa rona e entsoe ka lehlabathe la quartz le hloekileng haholo. Lihlahisoa li qhibiliha ka mocheso o phahameng ho fihlela 2500C seboping sa elektroniki. Lihlahisoa li na le thatafalo e phahameng ea mocheso o phahameng oa mamello ea mocheso, ho hanyetsa mahlaseli, ho ts'oaroa ha motlakase le ho khanna hantle, 'me li sebelisoa haholo indastering ea boenjineri, ea k'hemistri, ea elektroniki, ea tšepe le ea ts'ireletso. Khamphani ea rona e ka hlahisa boholo bo fapaneng ba silicon carbide, ho latela maemo a naha le a machabeng GB, ISO, ANSI, FEPA, JIS, jj.
Silicon carbide (SiC), e tsejoang hape e le carborundum, ke kompone ea silicon le khabone e nang le foromo ea lik'hemik'hale ea SiC. E hlaha ka tlhaho e le moissanite ea diminerale e sa tloaelehang haholo. Pente ea maiketsetso ea silicon carbide e hlahisitsoe ka bongata ho tloha ka 1893 hore e sebelisoe e le bohale. Lithollo tsa silicon carbide li ka hokahanngoa hammoho ka ho sintering ho etsa li-ceramics tse thata haholo tse sebelisoang haholo lits'ebetsong tse hlokang mamello e phahameng, joalo ka mariki a koloi, lithupa tsa koloi le lipoleiti tsa letsopa tse liaparong tse sireletsang likulo. Lisebelisoa tsa elektroniki tsa silicon carbide joalo ka li-diode tse bonesang khanya (li-LED) le li-detectors li-radios tsa pele li ile tsa bonts'oa ka lekhetlo la pele ho pota 1907. SiC e sebelisoa ho lisebelisoa tsa elektroniki tsa semiconductor tse sebetsang maemong a batang haholo kapa mehatong e phahameng, kapa ka bobeli. Likristale tse kholo tse le 'ngoe tsa silicon carbide li ka lengoa ka mokhoa oa Lely; li ka khaoloa ka mahakoe a tsejoang e le synthetic moissanite. Silicon carbide e nang le bokaholimo bo phahameng e ka hlahisoa ho tloha SiO2 e nang le lisebelisoa tsa semela.

(1) Sebōpi se seholo se qhibilihisang, nako e telele e qhibilihisang, e lebisa ho kristallishene e eketsehileng, likristale tse kholo, bohloeki bo phahameng le litšila tse fokolang ho hlahiseng silicon carbide.
(2) Sebopeho sa silicon carbide: Bothata bo botle, bophelo bo bolelele.
(3) Lik'hemik'hale tse hlatsoitsoeng le metsi a hlatsoitsoe hantle.
(4) Kalafo e khethehileng bakeng sa silicon carbide e fumana bohloeki bo phahameng, ho ba thata ho feta le ho sebetsa hantle.
3.Kopo
Silicon carbide e ka sebelisoa e le metallurgical deoxidizer le mocheso o phahameng o kenang thepa ho qhibilihisa.
Silicon carbide le eona e ka sebelisoa e le lisebelisoa tse khorisang, tse ka sebelisoang ho etsa lisebelisoa tse khorisang, joalo ka ho sila mabili, majoe a oli, ho sila hlooho joalo-joalo.
Silicon carbide ke mofuta o mocha oa mochini o matlafatsang oa tšepe o etsang deoxidizing agent le mochini o loketseng oa ho futhumatsa o chesang o sebelisetsoang ho thibela 'mele. Tekanyo ea ts'ebeliso ke 14kg / t e ka etsa ts'ebeliso ea motlakase ho fokotsa 15-20kw / h le nako ea ho fokotsa 15-20min ka sebōpi ho phahamisa tlhahiso ho 8-10%.
