maʻemaʻe 99.95% tungsten target tungsten disc no ka ʻoihana
He huahana i hana ʻia mai ka pauka tungsten maʻemaʻe a he ʻano keʻokeʻo kālā. He mea kaulana ia ma nā ʻano he nui ma muli o kāna mau waiwai kino a me kemika. ʻO ka maʻemaʻe o nā mea i hoʻopaʻa ʻia ʻo tungsten hiki ke piʻi i ka 99.95% a i ʻole ke kiʻekiʻe, a loaʻa iā lākou nā hiʻohiʻona e like me ka haʻahaʻa haʻahaʻa, kiʻekiʻe hoʻoheheʻe kiʻekiʻe, haʻahaʻa haʻahaʻa o ka hoʻonui, haʻahaʻa haʻahaʻa haʻahaʻa, non toxicity, a me non radioactivity. Eia kekahi, ʻoi aku ka maikaʻi o ka thermochemical paʻa o nā mea i hoʻopaʻa ʻia i ka tungsten a ʻaʻole kūpono i ka hoʻonui ʻana a i ʻole ka ʻoki ʻana, nā hopena kemika me nā mea ʻē aʻe, a me nā mea ʻē aʻe.

1. Aia kā mākou hale hana ma Luoyang City, Henan Province. He wahi hana ʻo Luoyang no nā mines tungsten a me molybdenum, no laila, loaʻa iā mākou nā mea maikaʻi loa i ka maikaʻi a me ke kumukūʻai;
2. Loaʻa i kā mākou hui nā limahana loea me ka ʻoi aku o 15 mau makahiki o ka ʻike, a hāʻawi mākou i nā hoʻonā a me nā manaʻo no kēlā me kēia mea kūʻai aku.
3. ʻO kā mākou huahana a pau e nānā pono i ka maikaʻi ma mua o ka lawe ʻia ʻana aku.
4. Inā loaʻa iāʻoe nā waiwai hemahema, hiki iāʻoe ke hoʻokaʻaʻike mai iā mākou no ka uku.
1.ʻO ke ʻano o ka pauka metallurgy
(E kaomi i ka pauka tungsten i ke ʻano a laila hoʻopaʻa ʻia i ka wela kiʻekiʻe i loko o ka lewa hydrogen)
2. Ka Hoʻomākaukau ʻana i nā Mea Kūlohelohe Sputtering
(Ka waiho ʻana o nā mea tungsten ma luna o kahi pani e hana i kahi kiʻiʻoniʻoni lahilahi)
3. kaomi isostatic wela
(Densification mālama ʻana i nā mea tungsten ma ka hoʻohana ʻana i ka mahana kiʻekiʻe a me ke kaomi kiʻekiʻe)
4.Melting ala
(E hoʻohana i ka wela kiʻekiʻe e hoʻoheheʻe loa i ka tungsten, a laila e hana i nā mea kikoʻī ma o ka hoʻolei ʻana a i ʻole nā kaʻina hana ʻē aʻe)
5. Waihona mahu mahu
(Ke ʻano o ka decomposing gaseous precursor ma ke kiʻekiʻe wela a me ka waiho ʻana i ka tungsten ma luna o ka substrate)
ʻenehana uhi kiʻiʻoniʻoni lahilahi: Hoʻohana nui ʻia nā pahuhopu Tungsten i nā ʻenehana uhi kiʻiʻoniʻoni lahilahi e like me ka hoʻoheheʻe kino kino (PVD) a me ka hoʻoheheʻe ʻana i ka mahu (CVD). Ma ke kaʻina hana PVD, ua hoʻokuʻu ʻia ka pahuhopu tungsten e nā ion ikehu kiʻekiʻe, e hoʻoheheʻe ʻia a waiho ʻia ma ka ʻili o ka wafer, e hana ana i kahi kiʻiʻoniʻoni tungsten. ʻO kēia kiʻiʻoniʻoni he paʻakikī kiʻekiʻe loa a me ke kūpaʻa ʻana, hiki ke hoʻomaikaʻi maikaʻi i ka ikaika mechanical a me ka lōʻihi o nā mea semiconductor. Ma ke kaʻina hana CVD, waiho ʻia nā mea i hoʻopaʻa ʻia ʻo tungsten ma ka ʻili o ka wafer ma o ka hopena kemika i ka wela kiʻekiʻe e hana ai i kahi uhi ʻaʻahu, kūpono loa ia no ka hoʻohana ʻana i nā mea hana semiconductor kiʻekiʻe a me nā alapine kiʻekiʻe.
Hoʻohana pinepine ʻia ʻo Molybdenum ma ke ʻano he mea paʻa i ka mammography ma muli o kāna mau waiwai maikaʻi no ke kiʻi ʻana i ka ʻiʻo umauma. He helu atomic haʻahaʻa ka Molybdenum, ʻo ia hoʻi, ʻo nā hihi X i hana ʻia he mea kūpono ia no ke kiʻi ʻana i nā mea palupalu e like me ka umauma. Hoʻopuka ʻo Molybdenum i nā kukui X maʻamau i nā pae ikehu haʻahaʻa, e hoʻolilo iā lākou i mea kūpono no ka nānā ʻana i nā ʻokoʻa liʻiliʻi o ka nui o ka umauma.
Eia kekahi, loaʻa i ka molybdenum nā waiwai conductivity thermal maikaʻi, he mea nui ia i nā mea hana mammography kahi i maʻa mau ai nā hōʻike X-ray. ʻO ka hiki ke hoʻopau maikaʻi i ka wela e kōkua i ka mālama ʻana i ke kūpaʻa a me ka hana o nā paipu X-ray i nā manawa lōʻihi o ka hoʻohana.
Ma ke ʻano holoʻokoʻa, ʻo ka hoʻohana ʻana i ka molybdenum ma ke ʻano he mea i hoʻopaʻa ʻia i ka mammography e kōkua i ka maikaʻi o ke kiʻi umauma ma o ka hāʻawi ʻana i nā waiwai X-ray kūpono no kēia noi kikoʻī.
ʻO ka haʻalulu kiʻekiʻe: He kiʻekiʻe ka haʻahaʻa o nā mea i hoʻopaʻa ʻia ʻo Tungsten a hiki ke hoʻopōʻino i ka hopena a me ka haʻalulu.
ʻO ke kumukūʻai hana kiʻekiʻe: He kiʻekiʻe ke kumukūʻai hana o ka tungsten target material no ka mea e koi ana kāna kaʻina hana i kahi ʻano o nā kaʻina hana paʻakikī a me nā mea hana kiʻekiʻe.
Paʻakikī paʻakikī: He mea paʻakikī ka welding tungsten target a koi aku i nā kaʻina hana wili kūikawā a me nā ʻenehana e hōʻoia i ka pono o kā lākou hana a me ka hana.
ʻO ke koena kiʻekiʻe o ka hoʻonui ʻana i ka wela: He kiʻekiʻe ka nui o ka hoʻonui ʻana o ka wela o ka Tungsten, no laila ke hoʻohana ʻia i nā wahi wela kiʻekiʻe, pono e nānā ʻia i kona nui hoʻololi a me ka hopena o ke kaumaha wela.
