MOCVD Substrate Heater, Mea Pumehana No MOCVD
Mea hoʻomehana graphite:
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:

ʻO ka mea hoʻomehana graphite no ka umu uila he mau waiwai o ka pale ʻana i ka wela, ke kū ʻana o ka oxidation, ka conductivity uila maikaʻi a me ka ʻoi aku o ka ikaika mechanical. Hiki iā mākou ke mīkini i nā ʻano mea hoʻomehana graphite e like me nā hoʻolālā o nā mea kūʻai aku.
