MOCVD Substrate Heater, Zvinhu Zvinodziisa zveMOCVD

Girafu yeGraphite:
Zvikamu zve graphite heater zvinoshandiswa muchoto chinodziya zvakanyanya, tembiricha inosvika 2200 degrees panzvimbo isina chinhu uye 3000 degrees munzvimbo ine gasi rakasanganiswa ne deoxidized.
Zvinhu zvikuru zve graphite heater:
1. kufanana kwechimiro chekudziyisa.
2. Kufambisa magetsi zvakanaka uye mutoro wemagetsi wakakwira.
3. kudzivirira ngura.
4. kusakwanisa kusvira.
5. kuchena kwakanyanya kwemakemikari.
6. simba guru remuchina.
Chakanakira ndechekuti inoshandisa simba shoma, inodhura zvakanyanya uye haina kugadziriswa zvakanyanya.
Tinogona kugadzira anti-oxidation uye hupenyu hurefu hwe graphite crucible, graphite mold uye zvikamu zvese zve graphite heater.
Zviyero zvikuru zve graphite heater:
