Nā ʻElemu Pumehana No MOCVD Substrate

Nā ʻElemu Pumehana No ke Kiʻi Hōʻikeʻike ʻia o MOCVD substrate

ʻO ka wehewehe pōkole:

ʻO Semicera's Heating Elements no MOCVD Substrate e hoʻolako ʻia e hāʻawi i ka mana wela kūpono a paʻa i nā kaʻina hana Metal-Organic Chemical Vapor Deposition (MOCVD). Hana ʻia mai ka graphite kiʻekiʻe, hāʻawi kēia mau mea hoʻomehana i ka conductivity thermal ʻokoʻa, ka hoʻomehana like ʻana, a me ka hilinaʻi lōʻihi. He kūpono no ka hana semiconductor, hana LED, a me nā noi waiwai holomua, ʻo nā mea hoʻomehana ʻo Semicera e hōʻoiaʻiʻo i ka hana maʻamau, e hoʻonui ana i kāu kaʻina MOCVD substrate no ka maikaʻi a me ka maikaʻi.

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.
