Hoʻopili ka hapa nui o ka poʻe i ka alumini me nā kini inu a me nā mōlina puka makani hoʻolālā. He kakaikahi ka poʻe i ʻike he ʻano ultra-refined o kēia metala maʻamau e noho ana ma ka puʻuwai o nā ʻenehana holomua loa o ka honua. ʻO ka alumini maʻemaʻe kiʻekiʻe, me ke koi honua makahiki he 300,000 a 400,000 metric tons wale nō, ʻoi aku ka liʻiliʻi ma mua o 1% o ka huina o ka puka alumini electrolytic mua, e kākoʻo ana i nā ʻāpana koʻikoʻi mai nā capacitors electrolytic a me ka hana semiconductor a hiki i nā mea hoʻolalelale particle. ʻO ia kekahi o nā mea holomua koʻikoʻi kahi e hana wikiwiki ai nā mea hana kūloko i nā holomua ʻenehana i nā makahiki i hala iho nei.
Ka Wehewehena a me ka Māhele Maʻemaʻe
Ua wehewehe ʻia ka alumini maʻemaʻe kiʻekiʻe e like mealumini me ka maʻemaʻe haʻahaʻa loao 99.99% (papa 4N), ʻoi aku ka maʻemaʻe ma mua o ka maʻemaʻe o ke alumini maʻemaʻe ʻoihana kalepa maʻamau 1000 series. I ka ʻenekinia mea, ua hoʻokaʻawale ʻia e ka pae maʻemaʻe, me kēlā me kēia papa e lawelawe ana i nā hana ʻoihana like ʻole:
- 3N (99.9%): Alumini maʻemaʻe ʻoihana, hoʻohana ʻia no ke kūkulu ʻana maʻamau a me nā kaʻa uila
- 4N (99.99%): Alumini maʻemaʻe kiʻekiʻe maʻamau, ka papa hana no nā foil capacitor electrolytic a me ka uhi optical
- 4N5 (99.995%): Alumini maʻemaʻe kiʻekiʻe waena, i kuhikuhi ʻia no nā capacitors kiʻekiʻe a me nā feedstock sputtering target
- 5N (99.999%): Alumini maʻemaʻe kiʻekiʻe loa, ke kumu hoʻohālikelike no nā pahuhopu sputtering semiconductor a me nā interconnects kaapuni i hoʻohui ʻia
- 6N (99.9999%): ʻAlumini maʻemaʻe papa uila, i mālama ʻia no ka noiʻi ʻoi loa a me nā mea hoʻokele super
ʻAʻole e like me nā mea hoʻohuihui alumini maʻamau, ʻaʻole ka waiwai o ka alumini maʻemaʻe kiʻekiʻe e waiho ana i ka ikaika mechanical. Loaʻa kona waiwai kalepa holoʻokoʻa mai nā waiwai kino kū hoʻokahi i hiki ai i kona ʻano haumia haʻahaʻa loa. Ua hoʻokaʻawale ʻia ʻo ia he mea hana, ʻaʻole he mea kūkulu.
Nā Kaʻina Hana Hana Hoʻomaʻemaʻe
Pono ka alumini electrolytic maʻamau i ka hoʻomaʻemaʻe lua e hiki ai i ka maʻemaʻe 4N a ʻoi aku. ʻEkolu mau ʻenehana hoʻomaʻemaʻe nui e hoʻomalu nei i ka ʻoihana, kēlā me kēia me nā palena maʻemaʻe like ʻole a me nā ʻano kumukūʻai:
1. ʻElekikolisis ʻekolu papa: Hoʻokō i ka maʻemaʻe 4N~4N5 me ka ʻenehana hana i hoʻomaʻamaʻa ʻia a ʻike ʻia, akā lawe i ka hoʻohana ikehu kiʻekiʻe. ʻO ia ke ala hana nui no ka alumini maʻemaʻe kiʻekiʻe o ka papa ʻoihana, me nā kumukūʻai hana waena a kiʻekiʻe.
2. Hoʻomaʻemaʻe hoʻokaʻawale: Hāʻawi i ka maʻemaʻe 4N5 ~ 5N me nā kumukūʻai hana hiki ke hoʻokele ʻia. Ua lilo ia i kaʻina hana nui no ka hana ʻana i ka pahuhopu sputtering a me ka meaʻai foil uila, e hāʻawi ana i kahi kaulike ikaika ma waena o ka hana a me ka hoʻokele waiwai.
3. Hoʻomaʻemaʻe ʻāpana: Hōʻea i ka maʻemaʻe 5N~6N, ʻo ia ka pae kiʻekiʻe loa e hiki ke hoʻokō ʻia ma ke kālepa, akā he haʻahaʻa loa ka hopena a me nā kumukūʻai kiʻekiʻe loa. Hoʻohana wale ʻia ia no ka noiʻi ʻepekema a me nā noi maʻemaʻe loa.
Nā Waiwai Mea Koʻikoʻi
ʻO ka hana kūikawā okumu mai ka alumini maʻemaʻe kiʻekiʻeʻehā mau ʻano kino wehewehe.
ʻO ka mea mua, hoʻokokoke kona conductivity uila i ka palena kumumanaʻo. Ma muli o ke kānāwai a Matthiessen, hoʻopilikia nā ʻātoma haumia i ka lattice kristal alumini a hana i nā kikowaena hoʻopuehu electron e keakea ana i ke kahe o ke au. ʻO ke ʻano o ka maʻemaʻe kiʻekiʻe he ʻano kristal kūpono loa, e hopena ana i ka conductivity uila kiʻekiʻe. Hiki i ka alumini papa 4N ke hōʻea i 98% o ka conductivity kumumanaʻo o ka alumini maʻemaʻe, e hāʻawi ana i ka hoʻomehana resistive haʻahaʻa a me ka pono ikehu kiʻekiʻe.
ʻO ka lua, hāʻawi ia i ka conductivity thermal maikaʻi loa. Loaʻa i ka alumini maʻemaʻe kiʻekiʻe kahi conductivity thermal o 235 ~ 240 W / (m · K), kokoke i ka maximum theoretical. ʻOiai ua pili pū ka hoʻoili wela i ka hoʻopuehu ʻana o ka haumia, hōʻemi pololei ka hoʻomaikaʻi ʻana i ka maʻemaʻe i ke kū'ē ʻana i ka thermal, e hana ana i ka mea kūpono no ka hoʻokele thermal mana kiʻekiʻe.
ʻO ke kolu, hōʻike ia i ka ductility a me ke ʻano hana kūikawā. Me ka aneane ʻole o nā pae hoʻoikaika i loaʻa i loko o kona microstructure, loaʻa i ka alumini maʻemaʻe kiʻekiʻe ka plasticity maikaʻi loa me ka elongation ma mua o 40%. He haʻahaʻa ka nui o ka paʻakikī hana, e ʻae ana iā ia e ʻōwili ʻia i loko o nā foil lahilahi loa e like me 5 micrometers, ma kahi o hoʻokahi hapaʻumi o ke anawaena o ka lauoho kanaka.
ʻO ka hā, hāʻawi ia i ke kūpaʻa ʻoi aku ka maikaʻi ma mua o ka palaho. Hoʻokumu maoli ka alumini maʻemaʻe kiʻekiʻe i kahi ʻili oxide Al₂O₃ mānoanoa a like ma luna o kona ʻili. ʻO ka haʻahaʻa o ka haumia, ʻo ia hoʻi ka emi ʻana o nā hemahema i loko o kēia papa oxide a me nā ʻokoʻa hiki ke palaho kūloko liʻiliʻi, e unuhi ana i ka hoʻomaikaʻi nui ʻana i ke kūpaʻa ʻana i ka palaho i nā wahi hana hoʻouka kaua.
Nā Noi ʻOihana Koʻikoʻi
Lawelawe ka alumini maʻemaʻe kiʻekiʻe i ʻehā mau ʻāpana ʻoihana waiwai nui, kēlā me kēia me nā koi mea paʻa.
1. Pepa hao capacitor electrolytic: ʻO kēia ka noi nui loa, e helu ana ma mua o 60% o ka hoʻohana ʻana o ka alumini maʻemaʻe kiʻekiʻe. Koi ia i ka maʻemaʻe 4N ~ 5N, ka microstructure texture cubic a me ka nui o ka palaoa i kāohi nui ʻia. Hoʻohana ʻia kēia mau foils i nā lako mana uila mea kūʻai aku, nā ʻōnaehana hoʻokele uila kaʻa ikehu hou, nā ʻāpana mana kikowaena 5G, nā mea hoʻololi alapine ʻoihana a me nā inverters photovoltaic. ʻO ke ʻano palaoa cubic pololei e hiki ai ke kālai like ʻana o nā pores tunnel, e hoʻonui ana i ka capacitance kikoʻī.
2. Hana ʻana i nā mea hana semiconductor a me nā mea uila: He ʻano maʻalahi loa nā mea hana semiconductor i ka haumia metala. Hoʻohana ʻia ka alumini maʻemaʻe kiʻekiʻe 5N+ no nā pahuhopu sputtering i nā kaʻina hana hoʻokaʻawale vapor (PVD) no nā papa interconnect chip, me nā haumia metala alkali i kāohi ʻia ma ka pae ppb. Hoʻohana ʻia nō hoʻi no nā mea electrode i nā kānana nalu acoustic o ka ʻili a me nā mea hana mana, a me nā substrates conductivity thermal kiʻekiʻe no ka hoʻopili ʻana i nā mea holomua.
3. Nā mea uila vacuum a me nā mea hoʻolalelale ʻāpana: ʻO kona hui pū ʻana o ka conductivity uila kiʻekiʻe, ka susceptibility magnetic haʻahaʻa loa a me ka helu outgassing haʻahaʻa ma lalo o ka vacuum e lilo ia i mea pono no nā keʻena vacuum accelerator ʻāpana, nā ʻano hana lua RF superconducting a me nā ʻāpana lako kukuna electron.
4. Nā ʻāpana Optical: Ma hope o ka poli pololei ʻana,hoʻokō ka alumini maʻemaʻe kiʻekiʻeʻoi aku ka noʻonoʻo ma mua o 90% ma ka spectrum ultraviolet a ma mua o 95% i ka mālamalama ʻike ʻia. Hoʻohana ʻia ia no nā aniani mīkini lithography ultraviolet hohonu, nā mea hoʻomālamalama ʻike mamao aerospace a me nā ʻōnaehana laser mana kiʻekiʻe.
Nā Pale ʻenehana a me ka Nānā ʻana i ka Mākeke
ʻEkolu mau pilikia loea nui ka hana ʻana i ka alumini maʻemaʻe kiʻekiʻe. ʻO ka mea mua, ʻo ia ka kaohi ʻana i ka haumia loa. No ka papa 4N, pono e mālama ʻia ka hao ma lalo o 20 ppm, ka silicon ma lalo o 15 ppm a me ke keleawe ma lalo o 10 ppm; no nā papa semiconductor 5N+, pono e kaohi ʻia nā metala alkali e like me ka sodium, potassium a me ka calcium ma lalo o 0.1 ppm, ʻo ka pae ppb no ka mea, ʻo nā nui liʻiliʻi like e hoʻohaʻahaʻa i ka hana o nā mea semiconductor. ʻO ka lua, ʻo ia ka mālama ʻana i nā wahi hana maʻemaʻe loa, e koi ana i nā uhi umu maʻemaʻe kiʻekiʻe a me ka hoʻoheheʻe ʻana o ka vacuum a i ʻole ka lewa pale e pale aku i ka haumia. ʻO ke kolu, ʻo ia ke kumukūʻai: ʻo ke kumukūʻai o ka alumini 4N he 3 ~ 5 mau manawa o ka alumini electrolytic maʻamau, ʻo ke kumukūʻai o ka papa 5N he 10 ~ 20 mau manawa, a ʻoi aku ka papa 6N ma mua o 50 mau manawa o ke kumukūʻai kumu, i hoʻokele ʻia e ka hoʻohana ʻana i ka ikehu kiʻekiʻe, ka emi ʻana o nā lako, nā hua haʻahaʻa a me nā ʻanuʻu hoʻomaʻemaʻe he nui.
I ka nānā ʻana i mua, ʻekolu mau ʻano nui e hoʻohālikelike i ka mākeke. E hoʻomau nā kaʻa ikehu hou a me nā photovoltaics i ka ulu ikaika ʻana o ke koi 4N. ʻO ka holomua ʻana i ka ʻenehana hoʻomaʻemaʻe hoʻokaʻawale e pani mālie i kekahi mana electrolysis ʻekolu-papa, e hoʻomaikaʻi ana i ka pono o ke kumukūʻai. ʻO ka mea nui loa, ʻo ka hoʻolalelale ʻana i ka localization semiconductor e hoʻokumu i ka koi wikiwiki no ka hoʻolako kūloko o ka alumini maʻemaʻe kiʻekiʻe 5N+ sputtering target grade.
Ma ke ʻano he mea hoʻolako kūikawā o nā huahana alumini ʻoihana e pili ana i nā pepa, nā kaola, nā paipu a me nā lawelawe mīkini kikoʻī, kākoʻo mākou i nā mea kūʻai aku ma nā ʻāpana uila, semiconductor a me ka ikehu hou me nā mea alumini kiʻekiʻe a me nā hoʻonā hana maʻamau. No nā nīnau e pili ana i nā kikoʻī alumini maʻemaʻe kiʻekiʻe a i ʻole ka hana ʻana i nā ʻāpana maʻamau, e kelepona i kā mākou hui kūʻai loea no ka ʻikepili huahana kikoʻī a me kahi ʻōlelo i hoʻopilikino ʻia.
