MOCVD Substrate Heater, Elemene Fa'avevela mo MOCVD

fa'avevela kafi:
O vaega faʻavevela graphite o loʻo faʻaaogaina i totonu o le ogaumu vevela maualuga ma le vevela e oʻo atu i le 2200 tikeri i le vacuum environment ma le 3000 tikeri i le siosiomaga kesi deoxidized ma faʻaofi.
Autu autu ole fa'avevela graphite:
1. tutusa o fausaga faamafanafana.
2. conductivity lelei eletise ma le mamafa eletise maualuga.
3. tete'e corrosion.
4. inoxidizability.
5. mama maualuga kemikolo.
6. malosi faʻainisinia maualuga.
O le lelei o le malosi lelei, maualuga le tau ma maualalo le tausiga.
E mafai ona tatou gaosia le anti-oxidation ma le umi o le ola o le graphite crucible, graphite mold ma vaega uma o le graphite heater.
Fa'ailoga autu ole fa'avevela graphite:
