He aha ka mea i hoʻohana ʻia ai ka pahu silika carbide?

ʻO Silicon Carbide (SiC) Crucibles he mau mea hoʻoheheʻe maikaʻi loa i hoʻolālā ʻia e hāʻawi i ka hana ʻokoʻa i nā noi ʻoihana like ʻole.Hoʻohana pono ʻia kēia mau crucibles e kū i nā wela kiʻekiʻe a hiki i 1600 ° C (3000 ° F), i mea kūpono no ka hoʻoheheʻe ʻana a me ka hoʻomaʻemaʻe ʻana i nā metala makamae, nā metala kumu, a me nā huahana like ʻole.

ʻO kekahi o nā pōmaikaʻi koʻikoʻi o ka SiC crucibles ko lākou kūpaʻa kiʻekiʻe i ka haʻalulu wela.ʻO ia ke ʻano hiki iā lākou ke kū i ka hoʻololi wikiwiki ʻana me ka ʻole o ka haki ʻana a i ʻole ka haki ʻana, e hōʻoiaʻiʻo ana i ka lōʻihi o ke ola ʻana a me ka hōʻemi ʻana i ka pono o ka hoʻololi pinepine ʻana.Ke hana nei ʻoe me ke gula, ke kālā, ke keleawe, a i ʻole nā ​​mea metala ʻē aʻe, ʻo SiC crucibles e hōʻoiaʻiʻo i ka hoʻoheheʻe ʻana a me ka hoʻomaʻemaʻe maikaʻi.

ʻO nā kīʻaha silika carbideloaʻa nā noi ma nā ʻoihana like ʻole, me ka hana ʻana i nā mea nani, ka hoʻolei ʻana metala, ka noiʻi noiʻi, a me ka hana ʻana i nā mea semiconductor.ʻO ko lākou hiki ke pale aku i nā wela kiʻekiʻe a me nā kaiapuni corrosive e lilo lākou i mea koho no ka poʻe loea i kēia mau kula.Hoʻohui, hāʻawi ʻo SiC crucibles i ka conductivity thermal maikaʻi loa, ka hopena i ka hoʻomehana ʻoi aku ka maikaʻi a hoʻomaikaʻi i ka hāʻawi ʻana i ka wela ma ke kaʻina hoʻoheheʻe.

I: Hoʻohana ʻia i ka ʻoihana hana mea nani

He kuleana koʻikoʻi ka SiC crucibles i ka hana ʻana i nā ʻāpana paʻakikī a paʻakikī.ʻO kēia mau crucibles e hōʻoia i ka mana pololei o ka mahana, a laila e ʻae i nā mea kūʻai aku e hoʻokō i ka kūlike a me ka maikaʻi i makemake ʻia i kā lākou huahana hope.Eia kekahi, hāʻawi ʻo SiC crucibles i kahi kaiapuni ʻole o ka haumia, e hōʻoiaʻiʻo ana e mālama ʻia ka maʻemaʻe o nā metala makamae ma ke kaʻina hoʻoheheʻe a hoʻomaʻemaʻe.

II: Hoʻohana ʻia i ka hoʻolei metala

Inā hoʻolei ʻia nā kiʻi keleawe a i ʻole ka hana ʻana i nā mea metala paʻakikī, hāʻawi kēia mau crucibles i ke kūpaʻa wela a me ka lōʻihi.ʻO ko lākou ʻano kemika a me ke ʻano non-reactive e kūpono iā lākou no ka lawelawe ʻana i kahi ākea o nā ʻāpana, me ka aluminika, ka hao, a me ka titanium.

III: Hoʻohana ʻia ma ke kaiāulu ʻepekema

Ke hilinaʻi pū nei ke kaiāulu ʻepekema i nā crucibles SiC no nā kumu noiʻi noiʻi like ʻole.Hoʻohana nui kēia mau crucibles i nā hoʻokolohua wela kiʻekiʻe a hiki ke kū i nā kaiapuni kemika ʻino.Mai ka noiʻi metallurgical a hiki i nā noiʻi ʻepekema waiwai, hāʻawi ʻo SiC crucibles i kahi hopena hilinaʻi a paʻa no nā mea noiʻi a me nā ʻepekema.

IV: Hoʻohana ʻia i ka hana semiconductor

ʻO ka hana ʻana o nā semiconductor e pili ana i nā kaʻina hana wela kiʻekiʻe, a ʻo ka hoʻohana ʻana i nā crucibles SiC e hōʻoia i ka mālama pono ʻana i ka mahana aʻo ka mālama ʻana i kahi kaiapuni ʻole.Hoʻohui ʻia, hāʻawi ʻo SiC crucibles i ke kūpaʻa maikaʻi loa i nā waikawa, alkalis, a me nā mea corrosive ʻē aʻe, e hoʻolilo iā lākou i kūpono no nā kūlana koʻikoʻi o ka hana semiconductor.

Hāʻawi ʻo SiC crucibles i nā mea maikaʻi ma mua o nā crucibles maʻamau i hana ʻia mai ka graphite a i ʻole ka pālolo.ʻOi aku ka pōkole o kēia mau crucibles ʻē aʻe a hiki ke hopena i ka haumia o ka metala i hoʻoheheʻe ʻia.ʻO ka SiC crucibles, ma ka ʻaoʻao ʻē aʻe, ʻoi aku ka lōʻihi o ke ola ʻana, e hōʻemi ana i ka downtime a hoʻonui i ka huahana.ʻO kā lākou kūpaʻa kemika kiʻekiʻe e pale i ka hopena makemake ʻole me nā metala hoʻoheheʻe, e hōʻoia ana i ka pae kiʻekiʻe o ka maʻemaʻe i nā huahana hope loa.

I ka hopena, he waiwai waiwai ʻo SiC crucibles no nā ʻoihana e koi ana i ka mālama pono ʻana i ka mahana a me kahi kaiapuni ʻole.ʻO ko lākou hiki ke kū i nā wela kiʻekiʻe, haʻalulu wela, a me nā kaiapuni kemika koʻikoʻi e lilo lākou i koho kūpono no ka hoʻoheheʻe ʻana a me ka hoʻomaʻemaʻe ʻana i nā metala makamae a me nā metala kumu.Mai ka hana ʻana i nā mea nani a hiki i ka hoʻolei metala a me ka hana semiconductor, hāʻawi ʻo SiC crucibles i ka hana ʻoi aku ka maikaʻi, hoʻonui i ka lōʻihi, a me ka hoʻomaikaʻi maikaʻi ʻana.
