Habka wax-soo-saarka warshadaha ee silikoon carbide-ka fal-celintu waa in laga soo saaro ciid quartz oo tayo sare leh iyo kookaha batroolka ee calcined ee foornada kuleylka korantada. The blocks carbide silicon la safeeyey waxaa laga sameeyey badeecooyin leh qaybinta size qayb kala duwan by burburinta, acid xoog leh iyo alkali dhaqidda, qalabka kala soocidda magnetic iyo baaritaanka ama kala soocidda biyaha.
Silicon carbide waxay leedahay laba nooc oo aasaasi ah oo caadi ah oo ah carbide silicon madow iyo carbide silicon cagaaran, kuwaas oo dhamaantood iska leh α-SiC. ① Carbide Silicon Black wuxuu ka kooban yahay 95% SiC, iyo ductility waa ka sarreeya carbide silicon cagaaran, kuwaas oo intooda badan loo isticmaalo si ay u soo saaraan oo ay farsameeyaan alaabta ceeriin oo leh awood yar oo adag, sida muraayadda la dahaadhay, dhoobo, dhagax, refractory, birta doofaarka iyo biraha qaaliga ah. ② Carbide silikoon cagaaran wuxuu ka kooban yahay SiC oo ku saabsan 97% kor ku xusan, is-afeynta ayaa wanaagsan, intooda badan waxaa loo isticmaalaa wax soo saarka iyo ka shaqeynta aaladaha carbide, birta titanium iyo muraayadaha indhaha, waxaana sidoo kale loo isticmaalaa in lagu buufiyo xargaha silsiladda iyo nadiifinta xawaaraha sare. qalabka birta. Intaa waxaa dheer, waxaa jira mitir cubic oo ah carbide silicon, taas oo ah crystal cagaaran iftiin ah oo lagu sameeyay hannaan cusub, waxaana loo isticmaalaa in lagu soo saaro caaryo ku habboon in lagu dhejiyo super-finishing, kaas oo ka dhigi kara qallafsanaanta dusha sare ee Ra32 ~ 0.16μm farsamaynta. ilaa 0.04 ~ 0.02μm.
Isticmaalka ugu muhiimsan ee falcelinta falcelinta silikoon carbide
(1) Maaddada xirashada, waxaa loo isticmaali karaa sidii caaryada, sida giraangiraha ciidda, dhagaxa dhagaxa, giraangiraha shiidada, foornada ciidda, iwm.
(2) Sida wakiilka deoxidizing iyo walxaha u adkaysta daxalka ee warshadaha birta. Silicon carbide inta badan waxa ku jira afar adeegsi oo waaweyn, kuwaas oo kala ah: dhoobada shaqaynaysa, maaddooyinka dib-u-celinta aadka u sarreeya, agabka adkaysiga xidhashada iyo dhalaalinta alaabta ceeriin. Marxaladdan, roughage silikoon carbide roughage waxaa lagu bixin karaa siyaabo badan, taas oo aan ahayn wax soo saarka tiknoolajiyada sare, iyo codsiga budada nano-silicon carbide ee leh maadada sayniska iyo tignoolajiyada aad u sareysa uma badna inay soo saarto saameyn miisaan leh muddada gaaban.
(3) Nadiifinta sare ee hal crystal, oo ku habboon wax soo saarka qalabka semiconductor, soo saarista fiilooyinka kiimikada carbide silicon.
Baaxadda codsiga: 3-12 cagood unugyo sawir-qaade ah, unugyo sawir-qaade, arsenide potassium, resonators quartz iyo jarista xariiqda kale. Warshadaha sawir-qaadista qoraxda, warshadaha semiconductor, silsiladda warshadaha piezoelectric crystal injineernimada mashruuca farsamaynta alaabta ceeriin.
Silikoon carbide sintering fal-celin ah - sababaha samaynta
Cadaadiska aadka u sarreeya iyo heerka heerkulka sare ee laga soo saaro xudunta dhulka ayaa lagu buufiyaa dhulka iyada oo la raacayo lafaha. Sida Thailand, Australia, Shiinaha Shandong, Maraykanka iyo dalal kale. Jaad birta ah waxaa lagu soo saaraa taabashada metamorphism. Sida Myanmar, Kashmir, Anhui ee Shiinaha iyo gobollo kale. Rubies aduunka waxaa inta badan laga soo min guuriyay meeleeyayaasha. Waa iyada oo loo marayo noocyo kala duwan oo emeralds ecological asalka ah, GEMS buluug by falcelinta isu-ururinta nabaad-guurka sintering silicon carbide la silikoon ore saafi ah dabiiciga ah, carbon, slag alwaax, cusbo warshadaha sida asal ahaan soo saaray alaabta ceeriin, in kululaynta foornada kululaynta korontada jiilka ka tarjumaysaa. Ku-darka alwaaxdu waa in la sameeyo qayb yar oo isku dhafan oo heerkul sare ah si loo soo saaro qaab-dhismeed jilicsan, kaas oo ku habboon inuu ka tarjumayo uumiga baaxadda weyn iyo isbeddelka laga soo saaro, si looga hortago shilalka qarxa, sababtoo ah jiilka. 1 tan oo ah carbide silikoon, ayaa laga yaabaa inay soo saarto qiyaastii 1.4t oo ah carbon monoxide (CO). Doorka cusbada warshadaha (NaCl) waxay ku haboon tahay in laga saaro aluminium oxide, xeryahooda iyo haraaga kale ee walxaha.
