Indlela yokukhiqiza yezimboni ye-silicon carbide e-reaction-sintered kufanele ibe sezingeni eliphezulu

Indlela yokukhiqiza yezimboni ye-silicon carbide e-reaction-sintered iwukukhipha isihlabathi se-quartz sekhwalithi ephezulu kanye ne-calcined petroleum coke esithandweni sokushisa sikagesi. Amabhulokhi e-silicon carbide acwengisisiwe enziwa izinto ezinazo zonke izinhlobo ezahlukene zobukhulu bezinhlayiya ngokuchoboza, ukuwasha okunamandla kwe-asidi kanye ne-alkali, imishini yokuhlukanisa ugesi kanye nokuhlola noma ukuhlukaniswa kwamanzi.

I-silicon carbide inezinhlobo ezimbili ezivamile ze-black silicon carbide kanye ne-green silicon carbide, zonke ezinge-α-SiC. ① I-black silicon carbide iqukethe cishe i-95% ye-SiC, futhi ukuqina kwayo kuphakeme kune-green silicon carbide, iningi lazo elisetshenziselwa ukukhiqiza nokucubungula izinto zokusetshenziswa ezinamandla aphansi okunamathela, njengengilazi elaminethiwe, i-porcelain, itshe, i-refractory, insimbi yengulube kanye nezinsimbi eziyigugu. ② I-green silicon carbide iqukethe i-SiC cishe ngo-97% ngaphezulu, ukuzilola kuhle, iningi lazo lisetshenziselwa ukukhiqiza nokucubungula amathuluzi e-carbide, insimbi ye-titanium kanye nama-lens optical, futhi lisetshenziselwa ukulola i-cylinder liner kanye nokupholisha amathuluzi ensimbi asheshayo. Ngaphezu kwalokho, kune-cubic metres ye-silicon carbide, okuyikristalu eluhlaza okotshani elakhiwe yinqubo entsha, futhi isetshenziselwa ukukhiqiza isikhunta esifanele ukuthwala i-super-finishing, okungenza ubulukhuni bomphezulu bube yi-Ra32 ~ 0.16μm kube ukucubungula ku-Ra0.04 ~ 0.02μm.

Ukusetshenziswa okuyinhloko kwe-silicon carbide eqeda ukusabela

(1) Njengento engagugi, ingasetshenziswa njengesikhunta, njengesondo lesihlabathi, itshe eligobile, isondo lokugaya, ithayela lesihlabathi, njll.

(2) Njenge-ejenti yokususa i-oxidizing kanye nezinto ezingamelana nokugqwala embonini yensimbi. I-silicon carbide ihlanganisa ikakhulukazi ukusetshenziswa okune okuyinhloko, okungukuthi: izinto zobumba ezisebenzayo, izinto eziqinile eziphikisayo, izinto ezingagugi kanye nezinto zokusetshenziswa zokuncibilikisa. Kulesi sigaba, i-silicon carbide roughage inganikezwa ngezindlela eziningi, okungewona umkhiqizo wobuchwepheshe obuphezulu, futhi ukusetshenziswa kwe-nano-silicon carbide powder enokuqukethwe okuphezulu kwesayensi nobuchwepheshe akunakwenzeka ukuthi kuveze imiphumela yesikali esikhathini esifushane.

(3) ikristalu elilodwa elihlanzekile kakhulu, elifanele ukukhiqizwa kwezinto ze-semiconductor, ukukhiqizwa kwemicu yamakhemikhali ye-silicon carbide.

Ububanzi bokusetshenziswa: Kwamaseli e-photovoltaic angamafidi angu-3-12, amaseli e-photovoltaic, i-potassium arsenide, ama-resonator e-quartz kanye nokunye ukusika kwemigqa. Imboni ye-solar photovoltaic, imboni ye-semiconductor, iphrojekthi yobunjiniyela be-piezoelectric crystal industry chain engineering processing.

I-silicon carbide e-reactive sintering - izizathu zokwakheka

Izinga lokucindezela okuphezulu kakhulu kanye nokushisa okuphezulu okukhiqizwa enkabeni yomhlaba kufefa emhlabathini nge-lava. NjengeThailand, e-Australia, eShandong yaseShayina, e-United States nakwamanye amazwe. I-jade yensimbi ikhiqizwa yi-touch metamorphism. NjengeMyanmar, eKashmir, e-Anhui yaseShayina nakwezinye izifunda. Ama-rubies emhlabeni atholakala kakhulu kuma-placers. Kuvela ngezinhlobonhlobo zama-emeralds okuqala emvelo, amagugu aluhlaza okwesibhakabhaka ngokuguguleka komswakama, ukusabela kokuhlanganiswa kwe-silicon carbide nge-silicon ore yemvelo emsulwa, ikhabhoni, i-slag yokhuni, usawoti wezimboni njengezinto zokusetshenziswa ezikhiqizwa ngokuyisisekelo, ekushiseni kukagesi, ukukhiqizwa okubonakalayo kokushisa kwesithando sokushisa. Ukwengezwa kwe-slag yokhuni ukwenza ucezu oluncane lwezinto ezixubile ekushiseni okuphezulu ukukhiqiza isakhiwo esinezimbobo, esivumelana nokubonakalisa umzimba womusi omkhulu kanye nokuguquguquka okufanele kususwe kukho, ukuvimbela izingozi zokuqhuma, ngenxa yokukhiqizwa kwe-1 ton ye-silicon carbide, kungakhiqiza cishe ama-1.4t e-carbon monoxide (CO). Indima kasawoti wezimboni (NaCl) ivumelana nokususa i-aluminium oxide, ama-compounds kanye nezinye izinsalela ezintweni.
