I-MOCVD Substrate heater, i-Heating Elements ye-MOCVD

Isifudumezi segraphite:
Amacandelo okufudumala kwegraphite asetyenziswa kwiziko lobushushu obuphezulu kunye nobushushu obufikelele kwi-2200 degree kwindawo ye-vacuum kunye ne-3000 degree kwindawo ye-deoxidized kunye ne-gas efakwe.
Iimpawu eziphambili zesifudumezi segraphite:
1. ukufana kwesakhiwo sokufudumala.
2. Ukuqhuba kakuhle kombane kunye nomthwalo ophezulu wombane.
3. ukumelana nomhlwa.
4. i-inoxidizability.
5. ukucoceka kweekhemikhali eziphezulu.
6. amandla aphezulu oomatshini.
Inzuzo inamandla okusebenza, ixabiso eliphezulu kunye nokugcinwa okuphantsi.
Sinokuvelisa i-anti-oxidation kunye nobomi obude be-graphite crucible, i-graphite mold kunye nazo zonke iindawo zesifudumezi se-graphite.
Iiparamitha eziphambili zesifudumezi segraphite:
