I-MOCVD Substrate Heater, Izinto Zokushisa ze-MOCVD

Isifudumezi se-Graphite:
Izingxenye zesifudumezi se-graphite zisetshenziswa esithandweni sokushisa okuphezulu lapho izinga lokushisa lifinyelela kuma-degree angu-2200 endaweni yokuhlanza kanye nama-degree angu-3000 endaweni yegesi ekhishwe i-oxidized nefakiwe.
Izici eziyinhloko ze-graphite heater:
1. ukufana kwesakhiwo sokushisa.
2. ugesi omuhle kanye nomthwalo omkhulu kagesi.
3. ukumelana nokugqwala.
4. ukungashisi.
5. ubumsulwa obuphezulu bamakhemikhali.
6. amandla aphezulu omshini.
Inzuzo ukuthi igcina ugesi ngendlela efanele, inenani eliphezulu kanye nokugcinwa kwayo kuphansi.
Singakhiqiza i-anti-oxidation kanye ne-graphite crucible ehlala isikhathi eside, isikhunta se-graphite nazo zonke izingxenye ze-graphite heater.
Amapharamitha ayinhloko we-graphite heater:

Ukucaciswa Kobuchwepheshe	I-VET-M3
Ubuningi (g/cm3)	≥1.85
Okuqukethwe Komlotha (PPM)	≤500
Ukuqina Kogu	≥45
Ukumelana Okuqondile (μ.Ω.m)	≤12
Amandla Okugobeka (i-Mpa)	≥40
Amandla Okucindezela (i-Mpa)	≥70
Usayizi Ophezulu Wokusanhlamvu (μm)	≤43
I-Coefficient Yokwanda Kokushisa Mm/°C	≤4.4*10-6

Isifudumezi se-graphite sesithando sikagesi sinezimpawu zokumelana nokushisa, ukumelana nokushiswa kwe-oxidation, ukuhanjiswa kukagesi okuhle kanye namandla angcono omshini. Singakwazi ukushisisa izinhlobo ezahlukene zesifudumezi se-graphite ngokwemiklamo yamakhasimende.
