Chidule cha ma disk a graphite

Maziko a miyala okhala ndi SIC okhala ndi chitsulo chopukutira ali ndi makhalidwe monga kukana kutentha kwambiri, kukana okosijeni, kuyera kwambiri, asidi, alkali, mchere ndi zinthu zachilengedwe, komanso ntchito yokhazikika ya thupi ndi mankhwala. Poyerekeza ndi graphite yoyera kwambiri, graphite yoyera kwambiri pa 400℃ imayamba okosijeni kwambiri, ngakhale kutentha sikuli kokwera kwambiri, kugwiritsidwa ntchito kwa nthawi yayitali kudzachitika chifukwa cha okosijeni ndi ufa, kudalira ntchito ndi tebulo kapena kuipitsa kwa kugwiritsa ntchito chilengedwe, kotero maziko a graphite okhala ndi SIC ngati zida zatsopano za MOCVD, njira yochotsera ufa pang'onopang'ono imalowa m'malo mwa graphite yoyera kwambiri.

Zinthu zazikulu:

1. Antioxidant yotentha kwambiri: antioxidant, ntchito ya antioxidant imakhala yabwino kwambiri pamene kutentha kuli pamwamba pa 1600℃;

2. Kuyera kwambiri: komwe kumapezeka pogwiritsa ntchito njira yosungira nthunzi ya mankhwala pansi pa kutentha kwambiri kwa chlorination;

3. Kukana kukokoloka kwa nthaka: kuuma kwambiri, pamwamba pokhuthala, tinthu tating'onoting'ono;

Kukana dzimbiri: asidi, alkali, mchere ndi zinthu zachilengedwe;

5. Gawo la pamwamba la SIC ndi β-silicon carbide, cubic yokhala ndi nkhope yozungulira.
