Cov yam ntxwv tseem ceeb ntawm graphite cua sov:
1. kev sib npaug ntawm cov qauv cua sov.
2. kev ua hluav taws xob zoo thiab kev thauj khoom hluav taws xob siab.
3. kev tiv thaiv corrosion.
4. tsis muaj zog.
5. tshuaj lom neeg huv siab.
6. lub zog kho tshuab siab.
Qhov zoo yog siv hluav taws xob tsawg, muaj nqis ntau thiab tsis tas yuav kho ntau. Peb tuaj yeem tsim cov khoom siv graphite uas tiv thaiv kev oxidation thiab siv tau ntev, xws li graphite pwm thiab txhua yam khoom siv graphite cua sov.

VET Zog yog lubChaw tsim khoom tiag tiag ntawm cov khoom siv graphite thiab silicon carbide uas muaj CVD txheej,muaj peev xwm muab khoomntau yamcov khoom siv kho kom haum rau kev lag luam semiconductor thiab photovoltaic. Okoj pab neeg kev tshaj lij los ntawm cov tsev kawm tshawb fawb hauv tsev sab saum toj, tuaj yeem muab cov kev daws teeb meem ntau duarau koj.
Peb pheej tsim cov txheej txheem siab heev los muab cov ntaub ntawv siab dua,thiabtau ua haujlwm tawm ib txoj kev siv tshuab tshwj xeeb uas tau txais patented, uas tuaj yeem ua rau kev sib txuas ntawm cov txheej thiab lub substrate nruj dua thiab tsis yooj yim tawg.
Fcov yam ntxwv ntawm peb cov khoom:
1. Kev kub siab oxidation tsis kam mus txog 1700℃.
2. Kev huv siab thiabkev sib npaug ntawm thermal
3. Kev tiv thaiv xeb zoo heev: kua qaub, alkali, ntsev thiab cov tshuaj reagents organic.
4. Kev nyuaj siab, qhov chaw me me, cov khoom me me.
5. Lub neej ua haujlwm ntev dua thiab ruaj khov dua
