Indlela yokuvelisa i-silicon carbide e-reaction-sintered silicon kufuneka ibe semgangathweni ophezulu

Indlela yokuvelisa i-silicon carbide e-reaction-sintered kukukhupha isanti ye-quartz esemgangathweni ophezulu kunye ne-calcined petroleum coke kwisithando sombane sokufudumeza. Iibhloko ze-silicon carbide ezicociweyo zenziwa izinto ezinokwabiwa kobukhulu obahlukeneyo ngokutyumza, ukuhlamba nge-asidi enamandla kunye ne-alkali, izixhobo zokwahlula ngemagnethi kunye nokucoca okanye ukwahlula ngamanzi.

I-silicon carbide ineentlobo ezimbini eziqhelekileyo ze-silicon carbide emnyama kunye ne-silicon carbide eluhlaza, zonke ezizeze-α-SiC. ① I-silicon carbide emnyama iqulethe malunga ne-95% ye-SiC, kwaye ukuguguleka kwayo kuphezulu kune-silicon carbide eluhlaza, uninzi lwazo lusetyenziselwa ukuvelisa nokucubungula izinto eziluhlaza ezinamandla aphantsi okutyhafa, njengeglasi elaminethiweyo, i-porcelain, ilitye, i-refractory, i-pig iron kunye neentsimbi ezixabisekileyo. ② I-silicon carbide eluhlaza iqulethe i-SiC malunga ne-97% ngaphezulu, ukuzilola ngokwayo kulungile, uninzi lwazo lusetyenziselwa ukuvelisa nokucubungula izixhobo ze-carbide, i-titanium metal kunye ne-optical lens, kwaye zikwasetyenziselwa ukulola i-cylinder liner kunye nokupolisha izixhobo zentsimbi ezikhawulezayo. Ukongeza, kukho ii-cubic metres ze-silicon carbide, eyikristale eluhlaza ekhanyayo eyenziwe yinkqubo entsha, kwaye isetyenziselwa ukuvelisa isikhunta esifanelekileyo sokuthwala i-super-finishing, enokwenza uburhabaxa bomphezulu ukusuka kwi-Ra32 ~ 0.16μm bube yi-processing ukuya kwi-Ra0.04 ~ 0.02μm.

Eyona ndlela iphambili yokusebenzisa i-reaction sintering silicon carbide

(1) Njengento engagugiyo, ingasetyenziswa njengesikhunta, njengevili lesanti, ilitye eligobileyo, ivili lokusila, ithayile yesanti, njl.njl.

(2) Njenge-arhente yokususa i-oxidizing kunye nezinto ezimelana nokugqwala kwishishini lesinyithi. I-silicon carbide ikakhulu ibandakanya iindlela ezine eziphambili zokusetyenziswa, ezizezi: iiseramikhi ezisebenzayo, izinto ezichasayo eziphezulu, izinto ezichasayo ukuguguleka kunye nezinto zokunyibilikisa. Kweli nqanaba, i-silicon carbide roughage inokubonelelwa ngeendlela ezininzi, ezingezizo iimveliso zobuchwepheshe obuphezulu, kwaye ukusetyenziswa kwe-nano-silicon carbide powder enomxholo ophezulu kakhulu wesayensi nobuchwepheshe akunakwenzeka ukuba kuvelise iziphumo zesikali kwixesha elifutshane.

(3) ikristale enye ecocekileyo kakhulu, efanelekileyo ekuveliseni izixhobo ze-semiconductor, ukuveliswa kweefayibha zeekhemikhali ze-silicon carbide.

Ububanzi besicelo: Kwiiseli ze-photovoltaic eziziimitha ezi-3-12, iiseli ze-photovoltaic, i-potassium arsenide, ii-quartz resonators kunye nezinye iindlela zokusika umgca. Ishishini le-photovoltaic lelanga, imboni ye-semiconductor, iprojekthi yobunjineli be-piezoelectric crystal industry chain processing material.

I-silicon carbide evuselelayo - izizathu zokwakheka

Uxinzelelo oluphezulu kakhulu kunye nomgangatho wobushushu obuphezulu obuveliswa embindini womhlaba utshizwa emhlabeni nge-lava. Ezifana neThailand, iOstreliya, iShandong yaseTshayina, iUnited States kunye namanye amazwe. I-steel jade iveliswa yi-touch metamorphism. Ezifana neMyanmar, iKashmir, iAnhui yaseTshayina kunye nezinye iindawo. Iirubhi ehlabathini zifumaneka ikakhulu kwii-placers. Ziphuma kwiindidi ezahlukeneyo zee-elektronikhi zendalo, amatye aluhlaza okwesibhakabhaka ngokukhukuliseka komxube we-reaction sintering silicon carbide kunye ne-silicon ore yendalo ecocekileyo, ikhabhoni, i-slag yomthi, ityuwa yemizi-mveliso njengezinto eziluhlaza eziveliswa ngokusisiseko, kwi-electrical heating furnace heating reflection. Ukongezwa kwe-slag yomthi kukwenza iqhekeza elincinci lezinto ezixutyiweyo kubushushu obuphezulu ukuvelisa isakhiwo esineembobo, esifanelekileyo ekubonakaliseni umzimba womphunga omkhulu kunye nokuguquguquka ekufuneka kususwe, ukuthintela iingozi zokuqhuma, ngenxa yokuveliswa kwetoni e-1 ye-silicon carbide, inokuvelisa malunga ne-1.4t ye-carbon monoxide (CO). Indima yetyuwa yemizi-mveliso (NaCl) ifanelekile ekususeni i-aluminium oxide, iikhompawundi kunye nezinye iintsalela kwizinto.
