MOCVD Substrate Heater, Cov Cuab Yeej Cuab Yeej Rau MOCVD

Graphite rhaub:
Cov khoom siv hluav taws xob graphite yog siv rau hauv qhov cub kub kub nrog qhov kub txog 2200 degree ntawm lub tshuab nqus tsev thiab 3000 degree hauv deoxidized thiab tso roj ib puag ncig.
Cov yam ntxwv tseem ceeb ntawm graphite rhaub:
1. uniformity ntawm cua sov qauv.
2. zoo hluav taws xob conductivity thiab siab hluav taws xob load.
3. corrosion kuj.
4. inoxidizability.
5. muaj tshuaj purity siab.
6. siab mechanical zog.
Qhov kom zoo dua yog lub zog txuag, tus nqi siab thiab kev saib xyuas qis.
Peb tuaj yeem tsim los tiv thaiv oxidation thiab lub neej ntev ntev graphite crucible, graphite pwm thiab txhua qhov chaw ntawm graphite rhaub.
