ʻO nā mea hoʻomehana graphite i uhi ʻia ʻo SiC maʻamau no nā wafers semiconductor

ʻO ka wehewehe pōkole:

WeiTai Energy Technology Co., Ltd. He mea hoʻolako alakaʻi o nā seramika semiconductor kiʻekiʻe a ʻo ia wale nō ka mea hana ma Kina e hiki ke hāʻawi manawaleʻa i ka silicon carbide ceramic maʻemaʻe kiʻekiʻe (ʻoi aku kaHoʻopili hou ʻia SiC) a me CVD SiC uhi.Eia kekahi, ua paʻa pū kā mākou hui i nā māla seramika e like me ke alumina, alumini nitride, zirconia, a me ka silicon nitride, etc.

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.
