Indlela yokuvelisa i-industrial-sintered silicon carbide kufuneka ibe kumgangatho ophezulu

Indlela yokuvelisa imveliso ye-react-sintered silicon carbide kukukhupha isanti ye-quartz ephezulu kunye ne-calcined petroleum coke kwisithando somlilo sombane. Iibhloko ze-silicon ecocekileyo ze-carbide zenziwe zibe yimpahla kunye neentlobo ezahlukeneyo zokusabalalisa ubungakanani be-particle ngokutyumza, i-asidi eqinile kunye nokuhlamba kwe-alkali, izixhobo zokuhlukana kwamagnetic kunye nokuhlola okanye ukuhlukana kwamanzi.

I-silicon carbide ineentlobo ezimbini eziqhelekileyo ezisisiseko ze-silicon carbide emnyama kunye ne-silicon carbide eluhlaza, zonke ezo ze-α-SiC. ① I-silicon carbide emnyama iqulethe malunga ne-95% ye-SiC, kwaye i-ductility yayo iphezulu kune-silicon carbide eluhlaza, uninzi lwayo lusetyenziselwa ukuvelisa kunye nokwenza izinto eziluhlaza ngamandla aphantsi, njengeglasi elaminethiweyo, i-porcelain, ilitye, i-refractory, intsimbi yehagu kunye iintsimbi ezixabisekileyo. ② I-silicon carbide eluhlaza iqulethe i-SiC malunga ne-97% apha ngasentla, ukuzilola ngokwakho kulungile, uninzi lwazo lusetyenziselwa ukuveliswa kunye nokulungiswa kwezixhobo ze-carbide, isinyithi se-titanium kunye ne-optical lens, kwaye zisetyenziselwa ukuhombisa i-cylinder liner kunye nokupolisha ngesantya esiphezulu. izixhobo zentsimbi. Ukongeza, kukho i-cubic metres ye-silicon carbide, eyikristale eluhlaza ekhanyayo eyenziwe yinkqubo entsha, kwaye isetyenziselwa ukuvelisa isikhunta esilungele ukuthwala ukugqiba okuphezulu, okunokwenza uburhabaxa bomphezulu ukusuka kwi-Ra32 ~ 0.16μm ukusetyenzwa ukuba Ra0,04 ~ 0.02μm.

Usetyenziso oluphambili lwe-reaction sintering silicon carbide

(1) Njengesixhobo sokugqoka, sinokusetyenziswa njengesikhunta, njengevili lesanti, i-whetstone, ivili lokugaya, i-sand tile, njl.

(2) Njenge-arhente ye-deoxidizing kunye ne-corrosion resistant material for metallurgical industry. I-Silicon carbide ibandakanya ikakhulu izinto ezine eziphambili, ezizezi: iiseramics ezisebenzayo, izixhobo ezinqandayo eziphezulu, izixhobo ezinganxibi kunye nokunyibilikisa izinto ezikrwada. Kweli nqanaba, i-silicon carbide roughage inokubonelelwa ngeendlela ezininzi, engeyiyo imveliso yobuchwepheshe obuphezulu, kwaye ukusetyenziswa kwe-nano-silicon carbide powder kunye nomxholo ophezulu kakhulu wesayensi kunye nobuchwepheshe akunakwenzeka ukuba kuvelise iziphumo zesikali kwixesha elifutshane.

(3) i-crystal eyodwa ecocekileyo, ilungele ukuveliswa kwezinto ze-semiconductor, ukuveliswa kwe-silicon carbide chemical fibers.

Ububanzi besicelo: Kwii-3-12 iinyawo ze-photovoltaic cells, iiseli ze-photovoltaic, i-potassium arsenide, i-quartz resonators kunye nezinye iindlela zokusika umgca. Umzi-mveliso weSolar photovoltaic, i-semiconductor industry, i-piezoelectric crystal industry chain chain project processing ekrwada.

I-silicon carbide esebenzayo esebenzayo-izizathu zokwakheka

Uxinzelelo oluphezulu kunye nomgangatho wobushushu obuphezulu oveliswe kumbindi womhlaba utshizwa ngaphandle komhlaba ngodaka. NjengeThailand, iOstreliya, iShandong yaseTshayina, iUnited States kunye namanye amazwe. Ijeyidi yentsimbi iveliswa yi-touch metamorphism. NjengeMyanmar, iKashmir, i-Anhui yaseChina kunye neminye imimandla. Iirubhi ehlabathini zithathwa ikakhulu kwiindawo zokubeka. Kungeentlobo ngeentlobo zee-emeralds zantlandlolo zendalo, amatye aluhlaza ngokhukuliseko oludibeneyo lwe-silicon carbide ene-silicon ecocekileyo yendalo, i-carbon, i-slag yomthi, ityuwa yamashishini njengezinto eziveliswa ngokusisiseko, kwiziko lokufudumeza lombane elibonakaliswe kwisizukulwana. Ukongezwa kwe-slag yokhuni kukwenza iqhekeza elincinci lezinto ezixubeneyo kwiqondo lokushisa eliphezulu ukuvelisa isakhiwo se-porous, esilungele ukubonakalisa umzimba womphunga omkhulu kunye nokuguquguquka apho ukususa, ukuthintela iingozi zokuqhuma, ngenxa yesizukulwana. ye-1 ton ye-silicon carbide, inokuvelisa malunga ne-1.4t ye-carbon monoxide (CO). Indima yetyuwa yezoshishino (NaCl) inceda ukususa i-aluminium oxide, i-compounds kunye nezinye iintsalela kwizinto eziphathekayo.
