MOCVD Substrate Heater, Mea Pumehana No MOCVD

ʻO ka wehewehe pōkole:

Hoʻohana ʻia nā mea hoʻomehana graphite i ka umu wela wela me ka mahana i hiki i ka 2200 degere ma ke kaiapuni vacuum a me 3000 degere i loko o ka deoxidized a hoʻokomo ʻia ke kinoea.
ʻO nā hiʻohiʻona nui o ka graphite heater:
1. kūlike o ka hoʻolālā hoʻomehana.
2. maikaʻi uila conductivity a kiʻekiʻe uila ukana.
3. pale ʻana i ka corrosion.
4. inoxidizability.
5. kiʻekiʻe kemika maemae.
6. ikaika mechanical kiʻekiʻe.
ʻO ka pōmaikaʻi, ʻoi aku ka maikaʻi o ka ikehu, ka waiwai kiʻekiʻe a me ka mālama haʻahaʻa.
Hiki iā mākou ke hana i ka anti-oxidation a me ke ola lōʻihi o ka graphite crucible, graphite mold a me nā ʻāpana āpau o ka graphite heater.
Nā palena nui o ka mea hoʻomehana graphite:
