Txoj kev tsim khoom lag luam ntawm cov tshuaj tiv thaiv-sintered silicon carbide yog kom tshem tawm cov khoom zoo quartz xuab zeb thiab calcined roj av coke nyob rau hauv hluav taws xob cua sov rauv. Lub refined silicon carbide blocks yog tsim los rau hauv cov khoom uas muaj ntau yam particle loj distributions los ntawm crushing, muaj zog acid thiab alkali ntxuav, sib nqus sib cais khoom thiab tshuaj ntsuam los yog dej sib cais.
Silicon carbide muaj ob hom yooj yim ntawm dub silicon carbide thiab ntsuab silicon carbide, tag nrho cov uas muaj nyob rau α-SiC. ① Dub silicon carbide muaj txog 95% SiC, thiab nws cov ductility yog siab dua ntsuab silicon carbide, feem ntau yog siv los tsim thiab ua cov ntaub ntawv raw uas tsis muaj zog tensile, xws li laminated iav, porcelain, pob zeb, refractory, npua hlau thiab cov hlau muaj txiaj ntsig. ② Ntsuab silicon carbide muaj SiC txog 97% saum toj no, nws tus kheej-sharpening yog qhov zoo, feem ntau yog siv rau kev tsim thiab ua cov cuab yeej carbide, titanium hlau thiab optical lo ntsiab muag, thiab tseem siv rau honing lub tog raj kheej liner thiab polishing high-speed. cov cuab yeej steel. Tsis tas li ntawd, muaj cov cubic meters ntawm silicon carbide, uas yog lub teeb ntsuab siv lead ua los ntawm cov txheej txheem tshiab, thiab yog siv los tsim cov pwm tsim rau cov kabmob super-tiav, uas tuaj yeem ua rau lub ntsej muag roughness ntawm Ra32 ~ 0.16μm ua haujlwm. Ra0.04 ~ 0.02μm.
Kev siv tseem ceeb ntawm cov tshuaj tiv thaiv sintering silicon carbide
(1) Raws li cov ntaub ntawv hnav-tiv taus, nws tuaj yeem siv los ua pwm, xws li xuab zeb log, whetstone, sib tsoo log, xuab zeb pobzeb, thiab lwm yam.
(2) Raws li tus neeg sawv cev deoxidizing thiab corrosion resistant khoom rau metallurgical kev lag luam. Silicon carbide feem ntau suav nrog plaub qhov kev siv tseem ceeb, uas yog: cov khoom siv ceramics, cov khoom siv high-end refractory, hnav-resistant cov ntaub ntawv thiab cov khoom siv raw. Nyob rau theem no, silicon carbide roughage tuaj yeem muab tau rau ntau txoj hauv kev, uas tsis yog cov khoom siv thev naus laus zis, thiab kev siv nano-silicon carbide hmoov nrog cov ntsiab lus tshawb fawb thiab thev naus laus zis siab heev tsis zoo li yuav tsim cov teebmeem hauv lub sijhawm luv.
(3) high-purity ib leeg siv lead ua, haum rau zus tau tej cov ntaub ntawv semiconductor, zus tau tej cov silicon carbide tshuaj fibers.
Scope ntawm daim ntawv thov: Rau 3-12 ko taw photovoltaic hlwb, photovoltaic hlwb, poov tshuaj arsenide, quartz resonators thiab lwm yam kab txiav. Hnub ci photovoltaic kev lag luam, kev lag luam semiconductor, piezoelectric siv lead ua kev lag luam saw engineering project raw khoom ua.
Reactive sintering silicon carbide - tsim yog vim li cas
Lub ultra-siab siab thiab kub tus qauv tsim nyob rau hauv lub ntiaj teb cov tub ntxhais yog sprayed tawm hauv av nrog cov lava. Xws li Thaib, Australia, Tuam Tshoj Shandong, Tebchaws Meskas thiab lwm lub tebchaws. Steel jade yog tsim los ntawm kov metamorphism. Xws li Myanmar, Kashmir, Tuam Tshoj Anhui thiab lwm thaj chaw. Rubies nyob rau hauv lub ntiaj teb no feem ntau yog muab los ntawm placers. Nws yog los ntawm ntau yam ecological emeralds, xiav lub pov haum los ntawm kev yaig aggregation cov tshuaj tiv thaiv sintering silicon carbide nrog cov ntshiab ntuj silicon ore, carbon, ntoo slag, muaj ntsev raws li qhov pib tsim cov khoom siv raw, hauv cov hluav taws xob cua sov cua sov cua sov ua kom pom txog tiam. Qhov sib ntxiv ntawm cov ntoo slag yog ua rau ib qho me me ntawm cov khoom sib xyaw ntawm qhov kub thiab txias los tsim cov qauv ntxeem tau, uas yog qhov tsim nyog rau kev xav txog qhov loj ntawm lub cev vapor thiab volatility los ntawm kev tshem tawm, tiv thaiv kev tawg tawg, vim yog tiam. ntawm 1 tuj ntawm silicon carbide, yuav tsim tau txog 1.4t ntawm carbon monoxide (CO). Lub luag haujlwm ntawm kev lag luam ntsev (NaCl) yog qhov tsim nyog rau kev tshem tawm aluminium oxide, cov tebchaw thiab lwm yam khoom seem hauv cov khoom.
