CAS 409-21-2 High purity silicon carbide hmoov nano SiC nanopowder thiab nanoparticles

Silicon carbide (SiC), tseem hu ua carborundum, yog ib qho sib xyaw ntawm silicon thiab carbon nrog cov tshuaj formula SiC. Nws tshwm sim nyob rau hauv qhov zoo li cov ntxhia tsis tshua muaj moissanite. Synthetic silicon carbide hmoov tau tsim tawm txij li xyoo 1893 los siv los ua cov tshuaj abrasive. Cov nplej ntawm silicon carbide tuaj yeem sib koom ua ke los ntawm sintering los tsim cov ceramics nyuaj heev uas tau siv dav hauv cov ntawv thov uas yuav tsum tau ua siab ntev, xws li tsheb nres, tsheb clutches thiab cov phaj ceramic hauv cov mos txwv vests. Kev siv hluav taws xob ntawm silicon carbide xws li lub teeb-emitting diodes (LEDs) thiab cov khoom siv hauv cov xov tooj cua thaum ntxov tau tshwm sim thawj zaug nyob rau xyoo 1907. SiC yog siv hauv cov khoom siv hluav taws xob semiconductor uas ua haujlwm ntawm qhov kub thiab txias, lossis ob qho tib si. Loj ib qho crystals ntawm silicon carbide tuaj yeem loj hlob los ntawm Lely txoj kev; lawv tuaj yeem txiav mus rau hauv lub pov haum hu ua hluavtaws moissanite. Silicon carbide nrog thaj chaw siab tuaj yeem tsim los ntawm SiO2 muaj nyob rau hauv cov khoom cog.
