Txoj kev tsim khoom lag luam ntawm cov silicon carbide reaction-sintered yog rho tawm cov xuab zeb quartz zoo thiab cov roj av calcined hauv lub cub tawg hluav taws xob. Cov silicon carbide refined blocks yog ua rau cov khoom lag luam nrog ntau qhov sib txawv ntawm cov khoom me me los ntawm kev tsoo, ntxuav cov kua qaub thiab alkali muaj zog, cov khoom siv sib cais sib nqus thiab kev tshuaj ntsuam lossis kev sib cais dej.
Silicon carbide muaj ob hom yooj yim ntawm cov silicon carbide dub thiab cov silicon carbide ntsuab, txhua yam uas yog α-SiC. ① Cov silicon carbide dub muaj li ntawm 95% SiC, thiab nws cov ductility siab dua li cov silicon carbide ntsuab, feem ntau yog siv los tsim thiab ua cov khoom siv raw nrog lub zog tensile qis, xws li iav laminated, porcelain, pob zeb, refractory, npua hlau thiab cov hlau muaj nqis. ② Cov silicon carbide ntsuab muaj SiC li ntawm 97% saum toj no, kev ua kom ntse tus kheej zoo, feem ntau ntawm lawv yog siv rau kev tsim thiab ua cov cuab yeej carbide, titanium hlau thiab optical lens, thiab kuj siv rau honing lub tog raj kheej liner thiab polishing cov cuab yeej hlau ceev ceev. Tsis tas li ntawd, muaj 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 nyog rau kev nqa super-finishing, uas tuaj yeem ua rau qhov roughness ntawm Ra32 ~ 0.16μm ua tiav rau Ra0.04 ~ 0.02μm.
Cov kev siv tseem ceeb ntawm kev sib xyaw ua ke ntawm silicon carbide
(1) Ua ib yam khoom siv uas tsis yooj yim hnav, nws siv tau ua pwm, xws li lub log xuab zeb, lub pob zeb whetstone, lub log sib tsoo, pobzeb xuab zeb, thiab lwm yam.
(2) Ua tus neeg sawv cev deoxidizing thiab cov khoom siv tiv taus corrosion rau kev lag luam metallurgical. Silicon carbide feem ntau suav nrog plaub qhov kev siv tseem ceeb, uas yog: cov khoom siv ceramics ua haujlwm, cov khoom siv refractory siab, cov khoom siv tiv taus hnav thiab cov khoom siv raw smelting. Nyob rau theem no, silicon carbide roughage tuaj yeem muab tau ntau txoj hauv kev, uas tsis yog cov khoom siv high-tech, thiab kev siv cov hmoov nano-silicon carbide nrog cov ntsiab lus scientific thiab technological siab heev yuav tsis tsim cov teebmeem nplai hauv lub sijhawm luv luv.
(3) cov khoom siv lead ua los ntawm cov khoom siv high-purity, tsim nyog rau kev tsim cov khoom siv semiconductor, kev tsim cov tshuaj silicon carbide fibers.
Scope ntawm daim ntawv thov: Rau 3-12 ko taw photovoltaic cells, photovoltaic cells, potassium arsenide, quartz resonators thiab lwm yam kab txiav. Kev lag luam photovoltaic hnub ci, kev lag luam semiconductor, piezoelectric crystal kev lag luam saw engineering project raw khoom ua.
Reactive sintering silicon carbide - cov laj thawj tsim
Cov txheej txheem siab heev thiab kub siab uas tsim tawm hauv lub ntiaj teb lub plawv yog txau tawm hauv av nrog cov lava. Xws li Thaib teb, Australia, Tuam Tshoj Shandong, Tebchaws Meskas thiab lwm lub tebchaws. Cov hlau jade yog tsim los ntawm kev kov metamorphism. Xws li Myanmar, Kashmir, Tuam Tshoj Anhui thiab lwm thaj chaw. Rubies hauv ntiaj teb feem ntau yog los ntawm placers. Nws yog los ntawm ntau yam ecological emeralds thawj, xiav gems los ntawm kev yaig aggregation reaction sintering silicon carbide nrog ntshiab ntuj silicon ore, carbon, ntoo slag, industrial ntsev ua cov khoom siv raw, hauv hluav taws xob cua sov cua sov reflective tiam. Ntxiv ntoo slag yog ua ib daim me me ntawm cov khoom sib xyaw ntawm qhov kub siab los tsim cov qauv porous, uas yog conducive rau reflecting lub cev loj thiab volatility uas yuav tshem tawm, los tiv thaiv kev tawg, vim yog tiam ntawm 1 tuj ntawm silicon carbide, yuav tsim tau txog 1.4t ntawm carbon monoxide (CO). Lub luag haujlwm ntawm industrial ntsev (NaCl) yog conducive rau kev tshem tawm txhuas oxide, cov tshuaj thiab lwm yam residues hauv cov khoom.
