Chotenthetsera cha MOCVD Substrate, Zinthu Zotenthetsera za MOCVD

Chotenthetsera cha graphite:
Zigawo za graphite heater zimagwiritsidwa ntchito mu uvuni wotentha kwambiri ndipo kutentha kumafika madigiri 2200 pamalo opumira mpweya ndi madigiri 3000 pamalo opumira mpweya.
Zinthu zazikulu za chotenthetsera cha graphite:
1. kufanana kwa kapangidwe ka kutentha.
2. kuyendetsa bwino magetsi komanso mphamvu zamagetsi zambiri.
3. kukana dzimbiri.
4. kusapha poizoni.
5. kuyera kwambiri kwa mankhwala.
6. mphamvu yayikulu yamakina.
Ubwino wake ndi kugwiritsa ntchito mphamvu moyenera, mtengo wake ndi wotsika komanso kusakonza bwino.
Tikhoza kupanga anti-oxidation ndi moyo wautali graphite crucible, graphite nkhungu ndi mbali zonse za graphite heater.
Magawo akuluakulu a chotenthetsera cha graphite:

Kufotokozera Zaukadaulo	VET-M3
Kuchuluka kwa Zinthu (g/cm3)	≥1.85
Phulusa (PPM)	≤500
Kulimba kwa Pagombe	≥45
Kukana Kwapadera (μ.Ω.m)	≤12
Mphamvu Yosinthasintha (Mpa)	≥40
Mphamvu Yokakamiza (Mpa)	≥70
Kukula kwa Tirigu Wapamwamba (μm)	≤43
Koyefiyira ya Kukulitsa Kutentha Mm/°C	≤4.4*10-6

Chotenthetsera cha graphite cha uvuni wamagetsi chili ndi mphamvu zotsutsana ndi kutentha, kukana okosijeni, kuyendetsa bwino magetsi komanso mphamvu yabwino ya makina. Tikhoza kupanga mitundu yosiyanasiyana ya chotenthetsera cha graphite malinga ndi mapangidwe a makasitomala.
