Silicon Carbide Wafer Disc yog cov khoom siv tseem ceeb siv hauv ntau cov txheej txheem tsim khoom semiconductor. peb siv peb cov cuab yeej patented los ua cov silicon carbide muaj kev nyab xeeb dua disc nrog purity siab heev, zoo txheej uniformity thiab ib tug zoo heev kev pab cuam lub neej, nrog rau cov tshuaj tiv thaiv siab thiab thermal stability.
VET Energy yog lub chaw tsim khoom tiag tiag ntawm cov khoom siv graphite thiab silicon carbide nrog cov txheej txheem sib txawv xws li SiC, TaC, pyrolytic carbon, glassy-carbon, thiab lwm yam., tuaj yeem muab ntau yam khoom siv rau kev lag luam semiconductor thiab photovoltaic. Peb pab neeg ua haujlwm los ntawm cov tsev kawm tshawb fawb saum toj kawg nkaus hauv tebchaws, tuaj yeem muab cov ntaub ntawv tshaj lij tshaj lij rau koj.
Peb tsis tu ncua tsim cov txheej txheem siab heev los muab cov ntaub ntawv zoo tshaj plaws, thiab tau ua haujlwm tawm cov cuab yeej tshwj xeeb patented, uas tuaj yeem ua rau kev sib txuas ntawm cov txheej thiab cov substrate nruj dua thiab tsis tshua muaj detachment.
Fnoj ntawm peb cov khoom:
1. Kub kub oxidation tsis kam mus txog 1700℃.
2. High purity thiabthermal uniformity
3. Zoo heev corrosion kuj: acid, alkali, ntsev thiab organic reagents.
4. High hardness, compact nto, zoo hais.
5. Lub neej ua haujlwm ntev dua thiab ruaj khov dua
