Silicon Carbide
Silicon carbide hmoov yog siab tshaj corundum nyob rau hauv abrasives thiab thib ob tsuas yog pob zeb diamond, cubic boron nitride thiab boron carbide. Qhov ntom ntom feem ntau suav tias yog gram / mm 3, thiab lub ntuj ntim ntom ntom ntawm silicon carbide abrasive yog nruab nrab ntawm gram / mm 3.Qhov muaj pes tsawg leeg ntawm silicon carbide feem ntau yog raws li cov roj av coke thiab cov khoom zoo silica ua cov ntaub ntawv tseem ceeb, ntxiv ntsev raws li ib tug additive, los ntawm cov kuj rauv kub kub smelting. Nws hardness yog nruab nrab ntawm corundum thiab pob zeb diamond 1, feem ntau yog siv rau 3-12 ntiv tes ntawm monocrystalline silicon, polysilicon, potassium arsenide, quartz siv lead ua hlau txiav. Nws yog cov khoom siv engineering ntawm hnub ci photovoltaic kev lag luam, kev lag luam semiconductor thiab piezoelectric siv lead ua kev lag luam.Qhov kev tsom xam thiab kev tshawb nrhiav txoj kev ntawm silicon carbide yog: cov ntsiab lus ntawm silicon carbide hauv silicon carbide txiav txim siab hardness ntawm silicon carbide zeb, particle loj ntawm silicon carbide. muaj kev cuam tshuam zoo rau kev txiav hlau, tab sis qhov tseem ceeb yog qhov particle zoo ntawm silicon carbide. Vim hais tias cov duab hloov ntawm silicon carbide rau dawb lub xeev txiav hais muaj ib qho tseem ceeb rau kev txiav efficiency thiab txiav zoo.
Cov khoom siv raw siv hauv cov xim dub silicon carbide muaj cov kev xav tau purity ntau dua, cov khoom zoo sib xws rau ntsuab silicon carbide, tab sis qhov kev ua tau zoo yog me ntsis nkig dua dub, thiab kuj muaj cov thermal conductivity zoo dua thiab cov yam ntxwv semiconductor, haum rau kev ua cov carbide, iav, ceramics thiab Cov ntaub ntawv tsis yog xim hlau, tab sis kuj rau cov ntaub ntawv semiconductor, kub silicon carbon pas nrig cua sov lub cev, deb infrared qhov chaw substrate thiab li on.Dub silicon carbide raws li cov duab yuav muab faib ua ca sib tsoo log, bevelled sib tsoo log, cylindrical sib tsoo log, khob sib tsoo log, disc sib tsoo log, thiab lwm yam .; Raws li daim ntawv cog lus yuav muab faib ua ceramic sib tsoo log, cob sib tsoo log, roj hmab sib tsoo log, hlau sib tsoo log, thiab lwm yam., nws cov yam ntxwv tsis yog abrasive, viscosity, hardness, daim ntawv cog lus, zoo, loj thiab lwm yam.
Dub silicon carbide particle loj xuab zeb yog quartz xuab zeb, roj av coke raws li cov ntaub ntawv tseem ceeb, los ntawm lub qhov cub ua hauj lwm kub kub smelting rau hauv silicon carbide raw block, thiab tom qab ntawd los ntawm lub tshuab sib tsoo ua tawg los ntawm kev tshuaj ntsuam, kua qaub thiab alkali ntxuav kom sib txawv. Specifications ntawm silicon carbide particle loj xuab zeb.Qhov hardness ntawm silicon carbide xuab zeb yog nruab nrab ntawm corundum thiab pob zeb diamond, cov neeg kho tshuab lub zog yog siab tshaj corundum, nkig thiab ntse, nrog ib tug tej yam hluav taws xob conductivity thiab thermal khoom.
Ntsuab silicon carbide hmoov Nta: 1, ntshiab silicon carbide yog xim tsis muaj xim, thiab muaj xim av rau dub yog vim impurity ntawm hlau. Ntsuab silicon carbide hmoov yog ntsuab, siv lead ua qauv, siab hardness, muaj peev xwm txiav, ruaj khov khoom, thermal conductivity.2, cov duab microscopic yog hexagonal siv lead ua, Mohs hardness ntawm silicon carbide yog 9.2, Vickers microhardness yog {{4. }} kg/mm 2, Knop hardness yog 2670-2815 kg/mm, microhardness yog 3300 kg ib cubic mm.3, ntsuab silicon carbide vim tshuaj stability, siab thermal conductivity, me thermal expansion coefficient, zoo hnav tsis kam, kev siv cov thermal conductivity zoo thiab thermal stability, raws li lub tshav kub exchanger, roj noj yog txo los ntawm 20%, roj txuag 35%, tus nqi nce los ntawm 20-30%.
