He aha nā mea hoʻohana o ka graphite crucible?

He aha ka graphite crucible?

graphite cruciblehe mea koʻikoʻi ka ʻāpana ʻoihana, i hoʻohana nui ʻia i nā ʻano ʻoihana like ʻole, e like me ka metallurgy, casting, machinery, chemistry, semiconductor, etc. I ka hana semiconductor, he hana koʻikoʻi ka graphite crucible a ʻo ia kekahi o nā mea pono i ka hana semiconductor.

He aha nā ʻano a me nā ʻano o nā crucibles graphite?

Nui nā ʻano o ka graphite crucibles, a he mau graphite crucibles kūpono no nā manawa like ʻole, e like me nā crucibles poepoe, square crucibles, integrated crucibles, etc.

Hiki ke hoʻokaʻawale ʻia nā crucibles graphite e like me nā kaiapuni hoʻohana like ʻole:
1. ʻO ke kīʻaha maʻamau: kūpono no ka hoʻoheheʻe ʻana, ka wela a me ka mālama ʻana i ka wela o nā metala maʻamau a me nā ʻāpana.
2. Kiʻekiʻe wela crucible: kūpono no ka hooheheeia refractory metala a me nā alaloa ma kiʻekiʻe wela, e like me tungsten, molybdenum, tantalum, etc.
3. Synthesis crucible: hoʻohana ʻia no ka synthesizing a me ka hoʻomākaukau ʻana i nā mea maʻemaʻe kiʻekiʻe, e like me nā mea semiconductor, nā mea ceramic, etc.
4. ʻO ka pahu pahu: kūpono no ka hoʻomehanaʻana a me ka hoʻoheheʻeʻana i loko o kahi'eneʻeneʻa, hoʻohana nuiʻia no ka hoʻomākaukauʻana i nā mea kūikawā a me ka hoʻoheheʻeʻana i nā metala maʻemaʻe kiʻekiʻe.

ʻO ka mea hana o ka graphite crucible maikaʻi ke kūpaʻa wela kiʻekiʻe a me ke kūpaʻa kemika. Hiki ke hoʻohana ʻia i ka mahana wela me ka ʻole o ka deformation a i ʻole ka pōʻino ma muli o ka wela kiʻekiʻe. I ka manawa like, loaʻa i ka graphite crucible ke kūpaʻa corrosion maikaʻi loa a hiki ke pale maikaʻi i ka erosion o nā mea kemika like ʻole, pēlā e hōʻoia ai i ka maikaʻi o ka hana ʻana o nā mea semiconductor.

He aha nā noi nui o nā crucibles graphite ma semiconductor?

I ke kaʻina hana semiconductor,graphite cruciblesHoʻohana nui ʻia e lawe a pale i nā ʻāpana semiconductor, a hiki ke hoʻololi maikaʻi i ka wela a me kēia manawa. Ma o ka lima a me ʻekolu mau paʻa paʻa ma ka lalo o ka graphite crucible, hiki ke hoʻokomo i ka nui o nā mea semiconductor i loko o ka graphite crucible i mea e pili pono ai lākou me ka graphite crucible, a laila e hoʻololi maikaʻi i ka wela a me kēia manawa.

Eia kekahi, hiki ke hoʻohana ʻia ka graphite crucible ma ke ʻano he conductor thermal a me ka uila. Ma muli o kona kiʻekiʻe thermal conductivity a me ka uila conductivity, graphite crucible hiki ke lawe i ka wela a me ke au mai waho o ka lako a hiki i nā ʻāpana semiconductor i loko o ka graphite crucible, a laila e hoʻomaʻamaʻa maikaʻi i nā ʻāpana semiconductor a me ka hoʻomalu ʻana i kēia manawa.

Eia kekahi, hiki i ka graphite crucible ke lawelawe ma ke ʻano he wela kūpono a me ka conductor uila, hiki ke hoʻokipa i ka nui o nā ʻāpana semiconductor, e ʻae ana i nā mea hana e hana i nā ʻāpana he nui i ka manawa like, pēlā e hoʻomaikaʻi ai i ka hana pono o nā mea hana.

He aha nā mea hoʻohana o ka graphite crucible i ka ʻoihana?

ʻO ke kūpaʻa wela kiʻekiʻe a me ke kūpaʻa kemika o ka graphite crucible hiki iā ia ke kū i ka hoʻoheheʻe metala ma nā wela kiʻekiʻe, e hōʻoia ana i ka maikaʻi a me ka paʻa o ka mea hoʻoheheʻe. No laila, hiki ke hoʻohana ʻia no ka hoʻomākaukau ʻana a me ka honi ʻana i nā mea metala like ʻole, e like me ke keleawe, aluminika, zinc, etc.

Eia kekahi, ʻoi aku ka maikaʻi o ka corrosion o nā crucibles graphite. He kūpaʻa ikaika ka graphite i ka nui o nā mea kemika a hiki ke pale aku i ka hoʻoheheʻe ʻana o nā mea ʻino e like me nā waikawa, alkalis, a me nā mea hoʻoheheʻe. No laila, hoʻohana pinepine ʻia nā crucibles graphite no ka mālama ʻana, mālama a hoʻopaʻa ʻana i nā mea corrosive. No ka laʻana, ma ka ʻoihana kemika, hiki ke hoʻohana ʻia nā crucibles graphite no ka pickling samples, dissolving substances, a me ka mālama ʻana i nā reagents acidic. I ka organik synthesis, hiki ke hoʻohana ʻia nā crucibles graphite no ka mālama ʻana i nā mea hoʻoheheʻe hopena a me nā catalysts, a me ka crystallization a me ka hoʻomaloʻo ʻana o nā mea organik.

Hōʻuluʻulu manaʻo

Ma kahi o kāna noi ʻana i ka hana semiconductor, hiki i nā crucibles graphite ke pāʻani i kahi hana koʻikoʻi i ka metallurgy, casting, machinery, chemistry a me nā māla ʻē aʻe. No ka laʻana, ma ka ʻoihana metallurgical, hiki ke hoʻohana ʻia nā crucibles graphite e hoʻoheheʻe a hoʻomaʻemaʻe i nā mea metala; i ka ʻoihana hoʻolei, hiki ke hoʻohana ʻia nā crucibles graphite e hoʻoheheʻe i nā mea metala a hana i nā huahana metala like ʻole; i loko o ka ʻoihana kemika, hiki ke hoʻohana ʻia nā crucibles graphite e like me nā reactors a i ʻole nā ​​​​mea pahu no nā hopena kemika. No laila, ʻaʻole ʻike wale ʻia ka waiwai o nā crucibles graphite i kāna mau noi noi, akā i kāna kuleana nui i ka hana ʻoihana. Me ka hoʻomau mau ʻana o ka ʻepekema a me ka ʻenehana, e ʻoi aku ka laulā o ka noiʻi o nā crucibles graphite.
