Indlela yokukhiqiza yezimboni ye-react-sintered silicon carbide kufanele ibe yekhwalithi ephezulu

Indlela yokukhiqiza yezimboni ye-react-sintered silicon carbide iwukukhipha isihlabathi se-quartz sekhwalithi ephezulu kanye ne-calcined petroleum coke esithandweni sokushisa sikagesi. Amabhulokhi e-silicon carbide acwengekile enziwa abe yimpahla enokusabalalisa kosayizi wezinhlayiyana ezihlukahlukene ngokuchotshozwa, i-asidi eqinile ne-alkali yokugeza, imishini yokuhlukanisa kazibuthe kanye nokuhlola noma ukuhlukaniswa kwamanzi.

I-Silicon carbide inezinhlobo ezimbili ezivamile eziyisisekelo ze-silicon carbide emnyama ne-silicon carbide eluhlaza, konke okungeze-α-SiC. ① I-silicon carbide emnyama iqukethe cishe u-95% we-SiC, futhi i-ductility yayo iphakeme kune-silicon carbide eluhlaza, iningi layo elisetshenziselwa ukukhiqiza nokucubungula izinto ezisetshenziswayo ezinamandla aphansi, njengengilazi elamiwe, i-porcelain, itshe, i-refractory, insimbi yengulube kanye izinsimbi eziyigugu. ② I-silicon carbide eluhlaza iqukethe i-SiC cishe ngama-97% ngaphezulu, ukuzilola ngokwakho kuhle, iningi lazo lisetshenziselwa ukukhiqizwa nokucutshungulwa kwamathuluzi e-carbide, insimbi ye-titanium namalensi optical, futhi asetshenziselwa ukucija isilinda liner nokupholisha ngesivinini esikhulu. amathuluzi ensimbi. Ngaphezu kwalokho, kukhona ama-cubic metres we-silicon carbide, okuyikristalu eluhlaza okhanyayo eyenziwe ngenqubo entsha, futhi isetshenziselwa ukukhiqiza isikhunta esifanele ukuthwala ukuqeda okuphezulu, okungenza ubulukhuni bobuso busuka ku-Ra32 ~ 0.16μm bucutshungulwe. ukuze Ra0,04 ~ 0.02μm.

Ukusetshenziswa okuyinhloko kwe-reaction sintering silicon carbide

(1) Njengempahla engagugi, ingasetshenziswa njengesikhunta, njengesondo lesihlabathi, i-whetstone, isondo lokugaya, i-sand tile, njll.

(2) Njenge-ejenti ye-deoxidizing kanye nezinto ezimelana nokugqwala embonini yensimbi. I-silicon carbide ikakhulukazi ihlanganisa ukusetshenziswa okune okuyinhloko, okungukuthi: izitsha zobumba ezisebenzayo, izinto eziphikisayo ezisezingeni eliphezulu, izinto ezingagugi kanye nezinto zokusetshenziswa ezincibilikayo. Kulesi sigaba, i-silicon carbide roughage ingahlinzekwa ngezindlela eziningi, okungewona umkhiqizo wobuchwepheshe obuphezulu, futhi ukusetshenziswa kwe-nano-silicon carbide powder enokuqukethwe okuphezulu kakhulu kwesayensi nobuchwepheshe mancane amathuba okuthi kukhiqize imiphumela yesikali esikhathini esifushane.

(3) ikristalu eyodwa ehlanzekile, elungele ukukhiqizwa kwezinto zokwakha ze-semiconductor, ukukhiqizwa kwe-silicon carbide chemical fibers.

Ububanzi bokusebenza: Kumamitha angu-3-12 amaseli e-photovoltaic, amaseli e-photovoltaic, i-potassium arsenide, ama-quartz resonators nokunye ukusika umugqa. Imboni ye-Solar photovoltaic, imboni ye-semiconductor, i-piezoelectric crystal industry chain engineering project processing impahla eluhlaza.

I-silicon carbide esebenzayo esebenzayo - izizathu zokwakheka

I-ultra-high kanye nezinga lokushisa eliphakeme elikhiqizwa enkabeni yomhlaba lifuthwa ngaphandle komhlaba ngodaka. NjengeThailand, i-Australia, iShandong yaseChina, i-United States namanye amazwe. I-Steel jade ikhiqizwa yi-touch metamorphism. NjengeMyanmar, Kashmir, Anhui yaseChina nezinye izifunda. Amarubi emhlabeni atholakala ikakhulukazi kuma-placers. Kungenxa yezinhlobonhlobo zama-emeralds asekuqaleni, amagugu aluhlaza okwesibhakabhaka ngokuhlangana kwe-erosion aggregation sintering i-silicon carbide ene-silicon ore yemvelo ehlanzekile, i-carbon, i-wood slag, usawoti wezimboni njengezinto ezingavuthiwe ezikhiqizwa ngokuyisisekelo, ekushiseni kukagesi kwesithando somlilo kuyaboniswa. Ukwengezwa kwe-slag yezinkuni ukwenza ucezu oluncane lwezinto ezixubene ekushiseni okuphezulu ukukhiqiza isakhiwo esinezimbotshana, esivumela ukukhombisa umzimba we-vapor omkhulu kanye nokuguquguquka okumele kususwe, ukuvimbela izingozi zokuqhuma, ngenxa yesizukulwane. yethani elingu-1 le-silicon carbide, ingakhiqiza cishe u-1.4t we-carbon monoxide (CO). Indima kasawoti wezimboni (NaCl) isiza ukususa i-aluminium oxide, izinhlanganisela nezinye izinsalela endabeni.
