ʻEkolu-petal crucible graphite no ka ulu ʻana o ke aniani semiconductor

ʻO ka wehewehe pōkole:

Ua hoʻolālā ʻia nā kīʻaha ʻekolu-lobed graphite o semicera no ka ulu ʻana o ke aniani semiconductor no nā noi semiconductor koi nui loa. Hāʻawi kā mākou crucibles i nā ʻāpana graphite isostatic kiʻekiʻe, e hōʻoiaʻiʻo ana i ka hana kiʻekiʻe kiʻekiʻe a me ka pale ʻana i ka corrosion. Hoʻonui ka hoʻolālā ʻekolu-lobed ʻokoʻa i ka conductivity thermal no ka ulu ʻana o ka kristal like ʻole a me nā hopena maikaʻi loa. Manaʻo mākou e lilo i hoa pili lōʻihi ma Kina.

graphite ʻekolu-petal crucibleno ka ulu ʻana o ke aniani semiconductor: Hana ʻia me nā mea maka maʻemaʻe kiʻekiʻe a hana ʻia ma o ka ʻenehana kikoʻī, loaʻa iā ia ke kūpaʻa kiʻekiʻe kiʻekiʻe, ka pale ʻana i ka corrosion, a me ka conductivity thermal. I ka hoʻohana ʻana i ka wela kiʻekiʻe, liʻiliʻi ka coefficient hoʻonui wela, a loaʻa iā ia kahi kūʻē i ka hoʻopaʻa ʻana i ka hoʻomehana wikiwiki a me ka hoʻomaha. Loaʻa iā ia ke kūpaʻa corrosion ikaika i ka waika a me ka hopena alkaline a me ke kūpaʻa kemika maikaʻi loa.

Ma ka laina huahana o semicera, hoʻolauna mākouIsostatic GraphiteNā ʻāpana i hoʻolālā ʻia no ka ulu ʻana o ke aniani semiconductor.

Ma semicera, hoʻokumu mākou i ka maikaʻi a me ka hana hou. Hoʻopili ʻia kā mākou crucibles meCVD SiC, ka mea e hoʻonui nui i ko lākou lōʻihi a me ke ola. Hoʻonui hou kēia uhi ʻokiʻoki i ko lākou kūʻē ʻana i nā kaiapuni kemika paʻakikī, e hoʻolilo iā lākou i koho hope loa no ka hana semiconductor.

No ka hoʻokō ʻana i nā koi koi o ka ʻoihana semiconductor no ka ulu ʻana o ka kristal pololei, ua hoʻohana mākou i nā kaʻina hana holomua e hōʻoia i kagraphite ʻekolu-petal cruciblehana maikaʻi ma nā kaiapuni like ʻole. ʻAʻole lawe wale kēia huahana i ka inoa brand semicera, akā hōʻike pū kekahi i kā mākou kūpaʻa i ka hana ʻenehana a me ka maikaʻi maikaʻi.

ʻAʻole i hoʻolālā wale ʻia ka Graphite three-petal crucible me ka noʻonoʻo ʻana, akā ke hoʻokō nei i ka mana maikaʻi a me ka hoʻāʻo ʻana e hōʻoia i kēlā me kēia huahana i nā kūlana kiʻekiʻe. Inā ma ka noiʻi noiʻi a i ʻole nā noi ʻenehana, hiki i kā mākou Graphite three-petal crucible ke hana paʻa a hilinaʻi e kōkua iā ʻoe e hoʻokō i kahi kiʻekiʻe o ka ulu ʻana o ka kristal semiconductor.

Ke koho ʻoe i ka Graphite three-petal crucible mai semicera, ʻaʻole wale ʻoe e loaʻa ka hana maikaʻi loa, akā hilinaʻi pū kekahi i ka ʻenehana hou. E ʻike i kā mākou huahana i kēia manawa a ʻike i nā hiki pau ʻole i lawe ʻia e ka maikaʻi maikaʻi loa!

ʻO nā huahana koʻikoʻi o semicera he graphite i hoʻohana ʻia i loko o nā semiconductors. ʻO ka ʻike kumu o ka honua holoʻokoʻa ʻo German SGL a me Iapana Toyo carbon huahana penei:

Palekana hana	semicera	SGL R6510	TOYO IG310
ʻAno nui (g/cm3)	1.91	1.83	1.85
Ka ikaika kulou (MPa)	8-10	60	49
Ka ikaika compressive (MPa)	135	130	103
Paʻa Paʻa (HS)	70	64	60
ʻO ke kau wela wela(W/m·K)	85	105	130
Coefficient o ka hoonui wela（10-6/K）	5.85	4.2	5.0
ka pale ʻana (μΩm)	11-13	13	10

Pono hana:
1. He maikaʻi a paʻa ka hoʻolālā, a maikaʻi ke kūlike.
2.Low coefficient o ka hoʻonui ʻana i ka wela, maikaʻi loa ke kūʻē ʻana i ka haʻalulu wela;
3.Isotropy;
4.Strong kemika kū'ē;
5.Good thermal a me ka uila conductivity;
6.It i maikai machining waiwai.

Nā mea kumu nui no ka ʻoihana o kēia wā
1. ʻOihana Semiconductor
2. ʻoihana ikehu lā
3. ʻoihana aerospace
4. ʻO ka ʻoihana nuklea

ʻO Semicera isostatic pressed graphite project, ua hana ʻia ma o ka hana nui e loaʻa ai ka kiʻekiʻe kiʻekiʻe, ka maʻemaʻe kiʻekiʻe, ka ikaika kiʻekiʻe, nā huahana graphite nui.
