Lub nkoj silicon carbide wafer yog lub cuab yeej thauj khoom rau cov wafer, feem ntau yog siv rau hauv cov txheej txheem diffusion hnub ci thiab semiconductor. Nws muaj cov yam ntxwv xws li kev hnav tsis kam, kev tiv thaiv corrosion, kev cuam tshuam kub siab, kev tiv thaiv plasma bombardment, muaj peev xwm dais kub siab, kev ua haujlwm thermal siab, kev tso cua sov siab, thiab kev siv mus sij hawm ntev uas tsis yooj yim khoov thiab deform. Peb lub tuam txhab siv cov khoom siv silicon carbide purity siab los xyuas kom meej tias lub neej ua haujlwm thiab muab cov qauv tsim tshwj xeeb, suav nrog ntau yam ntsug thiab kab rov tav wafer nkoj.
