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 VET Energy ka kamea hana maoli o ka graphite maʻamau a me nā huahana silicon carbide me ka uhi CVD,hiki ke hoolakoʻokoʻanā ʻāpana i hana ʻia no ka semiconductor a me ka ʻoihana photovoltaic. OʻO kāu hui ʻenehana mai nā keʻena noiʻi kūloko kiʻekiʻe, hiki ke hāʻawi i nā ʻoihana ʻoihana ʻoi aku ka nuināu.
Hoʻomau mau mākou i nā kaʻina hana kiʻekiʻe e hāʻawi i nā mea ʻoi aku ka holomua,aUa hana ʻo ia i kahi ʻenehana patented kūʻokoʻa, hiki iā ia ke hana i ka hoʻopaʻa ʻana ma waena o ka uhi a me ka substrate i ʻoi aku ka paʻa a emi ʻole i ka wehe.
