MOCVD Substrate Heater, Lisebelisoa tsa ho futhumatsa bakeng sa MOCVD

Mofuthu oa graphite:
Likarolo tsa heater ea graphite li sebelisoa seboping sa mocheso o phahameng se nang le mocheso o fihlang likhatong tse 2200 sebakeng sa vacuum le likhato tse 3000 tikolohong ea khase e nang le deoxidized le e kentsoeng.
Lintlha tse ka sehloohong tsa heater ea graphite:
1. ho tšoana ha mohaho oa ho futhumatsa.
2. conductivity e ntle ea motlakase le mojaro o phahameng oa motlakase.
3. ho hanyetsa kutu.
4. inoxidizability.
5. bohloeki bo phahameng ba lik'hemik'hale.
6. matla a phahameng a mechine.
Molemo ke matla a matla, boleng bo phahameng le tlhokomelo e tlaase.
Re ka hlahisa anti-oxidation le nako e telele ea bophelo ba graphite crucible, hlobo ea graphite le likarolo tsohle tsa heater ea graphite.
Lintlha tse ka sehloohong tsa heater ea graphite:

Tlhaloso ea Setsebi	VET-M3
Boima ba Bongata (g/cm3)	≥1.85
Litaba tsa Molora (PPM)	≤500
Bothata ba Lebopo	≥45
Khanyetso e Khethehileng (μ.Ω.m)	≤12
Flexural Strength (Mpa)	≥40

Mofuthu oa graphite bakeng sa sebōpi sa motlakase o na le thepa ea ho hanyetsa mocheso, ho hanyetsa oxidation, conductivity e ntle ea motlakase le matla a molemo a mochine. Re ka sebelisa mefuta e fapaneng ea heater ea graphite ho latela meralo ea bareki.
