Textured Cu substrates yog tsim los ntawm peb txheej (thickness ntawm 0.1mm, dav ntawm 10mm) (Duab: Kev Lag Luam Hlau)
TOKYO–(BUSINESS WIRE)–Tanaka Holdings Co., Ltd. (Lub taub hau: Chiyoda-ku, Tokyo; Tus Neeg Sawv Cev Tus Thawj Coj & CEO: Akira Tanae) hnub no tshaj tawm tias Tanaka Kikinzoku Kogyo KK (Lub Chaw Haujlwm Lub Taub Hau: Chiyoda-ku, Tokyo; Tus Neeg Sawv Cev Tus Thawj Coj & CEO: Akira Tanae) tau tsim cov kab tsim tshwj xeeb rau textured Cu hlau substrates rau YBCO superconducting hlau (*1) thiab tau tsim cov txheej txheem ntau lawm rau kev siv pib lub Plaub Hlis 2015.
Thaum Lub Kaum Hli 2008, Tanaka Kikinzoku Kogyo ua ke nrog Chubu Hluav Taws Xob Hluav Taws Xob thiab Kagoshima University tau sib koom ua ke tsim thawj cov khoom siv Cu hlau substrates siv superconducting hlau. Kev tsim khoom pib thiab cov qauv raug faib tawm txij lub Kaum Ob Hlis ntawm tib lub xyoo. Qhov no superconducting hlau hloov kev siv Ni alloys (nickel thiab tungsten alloys), uas yog yav tas los cov ntaub ntawv tseem ceeb rau textured hlau substrates, nrog tus nqi qis thiab siab orientation (*2) tooj liab, yog li txo cov nqi ntau dua 50%. Ib qho ntawm qhov tsis muaj zog ntawm tooj liab yog nws qhov tsis zoo rau oxidation, uas tuaj yeem ua rau cov yeeb yaj kiab nyias (superconducting hlau lossis oxide tsis txheej) tsim rau ntawm lub substrate los ua detached. Txawm li cas los xij, kev taw qhia thiab qhov smoothness yog nce los ntawm kev siv cov tshuaj tshwj xeeb npib tsib xee plating uas muaj palladium raws li cov pa hlau thaiv txheej, uas txhim kho qhov kev ruaj ntseg ntawm cov zaj duab xis nyias ntawm cov substrate.
Txij li cov qauv ntawm cov ntaub ntawv Cu substrates tau raug xa tawm thawj zaug, Tanaka Kikinzoku Kogyo tau txuas ntxiv mus ua kev tshawb fawb los txheeb xyuas qhov kev ruaj ntseg deposition. Kev tsim cov elongated substrates tau tam sim no ua tau los ntawm kev ua kom zoo ntawm cov khoom siv. Txhawm rau teb rau cov kev xav tau hauv tsev thiab thoob ntiaj teb tam sim ntawd, ib qho kev tsim khoom tshwj xeeb tau tsim los ntawm cov tuam txhab tsim cov nroj tsuag thaum lub Plaub Hlis 2015. Nws xav tias cov cuab yeej no yuav raug muab tso rau hauv ntau lwm yam kev lag luam yav tom ntej nrog rau kev mus ntev thiab Cov khoom siv hluav taws xob muaj peev xwm loj, Sib Nqus Resonance Imaging (MRI) thiab Nuclear Magnetic Resonance (NMR), uas yuav tsum muaj cov hlau nplaum sib nqus, thiab cov motors rau cov nkoj loj. Tanaka Kikinzoku Kogyo yog lub hom phiaj kom ua tiav kev muag khoom txhua xyoo ntawm 1.2 billion yen los ntawm xyoo 2020.
Ib qho piv txwv ntawm cov substrate no siv superconducting hlau tau ua tiav nyob rau ntawm 2nd High-function Hlau Expo thaum lub Plaub Hlis 8 thiab Plaub Hlis 10, 2015, ntawm Tokyo Big Sight.
* 1 YBCO superconducting wireSuperconducting cov ntaub ntawv ua tiav rau kev siv raws li cov hlau uas ua tiav xoom hluav taws xob tsis kam. Nws yog tsim los ntawm yttrium, barium, tooj liab thiab oxygen.
* 2 OrientationQhov no qhia txog qib ntawm uniformity nyob rau hauv orientation ntawm crystals. Qhov ntau dua ntawm superconductivity tuaj yeem tau txais los ntawm kev teeb tsa cov muaju ntawm cov ntu ntu.
Superconducting xov hlau muaj cov yam ntxwv ntawm kev tsim cov hlau nplaum muaj zog thaum coiled. Lawv raug cais raws li qhov ntsuas kub tseem ceeb (qhov kub uas lawv ua tiav superconductivity). Ob hom yog "high-temperature superconducting wire," uas tswj superconductivity ntawm -196 ° c los yog qis dua, thiab "kub-kub superconducting hlau," uas tswj superconductivity ntawm -250 ° c lossis qis dua. Nyob rau hauv kev sib piv rau low-temperature superconducting wire, uas twb tau siv rau MRI, NMR, linear motorcars thiab ntau dua, high-temperature superconducting hlau muaj qhov tseem ceeb tshaj tam sim no ceev (qhov loj ntawm hluav taws xob tam sim no), txo tus nqi los ntawm kev siv kua nitrogen kom txias. , thiab txo qhov cuam tshuam rau cov teebmeem ntawm sab nraud magnetic teb, yog li txoj kev loj hlob ntawm high-temperature superconducting hlau tam sim no tau nce.
Muaj bismuth-based (hu ua "bi-based" hauv qab) thiab yttrium-based (hu ua "Y-raws" hauv qab) cov xov hlau kub kub superconducting. Bi-raws li tau ntim rau hauv cov yeeb nkab nyiaj uas tau ua tiav txhawm rau ua kom nws siv tau raws li cov xaim, thaum Y-raws li tau muab pov tseg rau ntawm lub substrate nyob rau hauv ib daim kab xev nrog cov pob zeb sib xyaw kom siv tau los ua cov hlau. Y-raws li yuav tsum yog tiam tom ntej ntawm superconducting hlau vim nws muaj qhov tshwj xeeb tseem ceeb tam sim no ceev, muaj zog sib nqus cov yam ntxwv, thiab cov nqi ntawm cov ntaub ntawv tuaj yeem txo qis los ntawm kev txo cov nyiaj siv.
Yam ntxwv ntawm Y-raws li superconducting hlau substrates thiab kev tsim kho ntawm Tanaka Kikinzoku Kogyo
Hais txog Y-based superconducting hlau substrates, peb tab tom ua R&D rau "IBAD substrates" thiab "textured substrates." Cov yam ntxwv ntawm superconductivity yog nce los ntawm kev npaj cov hlau crystals ntawm lub sijhawm tsis tu ncua, yog li cov txheej txheem ntawm cov hlau yuav tsum tau ua tiav ntawm txhua txheej uas ua rau daim kab xev. Rau IBAD substrates, ib tug oxide nyias zaj duab xis yog taw qhia cov txheej txheem uas tsis muaj zog ntawm cov khoom siv tsis muaj zog, thiab nws tseem tsa qhov teeb meem ntawm tus nqi ntawm cov khoom siv thiab cov khoom siv. Qhov no yog vim li cas Tanaka Kikinzoku Kogyo tau tsom mus rau textured substrates. Cov nqi raug txo los ntawm kev siv cov khoom siv high-orientation tooj liab raws li cov khoom siv substrate, uas kuj ua rau cov neeg kho tshuab muaj zog thaum ua ke nrog cov khoom siv ntxiv dag zog siv cov cuab yeej siv clad uas tsis cuam tshuam rau kev taw qhia.
Tsim los ntawm 1885, Tanaka Precious Metals tau tsim ntau hom kev lag luam uas tsom mus rau kev siv cov hlau muaj txiaj ntsig. Thaum lub Plaub Hlis 1, 2010, pawg tau hloov kho nrog Tanaka Holdings Co., Ltd. ua lub tuam txhab tuav (niam txiv tuam txhab) ntawm Tanaka Precious Metals. Ntxiv nrog rau kev ntxiv dag zog rau kev tswj hwm kev lag luam, lub tuam txhab muaj lub hom phiaj los txhim kho kev pabcuam tag nrho rau cov neeg siv khoom los ntawm kev ua kom muaj kev tswj hwm zoo thiab kev ua haujlwm zoo ntawm kev ua haujlwm. Tanaka Precious Metals tau cog lus, ua ib lub koom haum tshwj xeeb, muab ntau yam khoom los ntawm kev koom tes ntawm pab pawg tuam txhab.
Tanaka Precious Metals yog nyob rau hauv cov chav kawm sab saum toj hauv Nyij Pooj hais txog qhov ntim ntawm cov hlau muaj txiaj ntsig, thiab tau ntau xyoo cov pab pawg tau tsim thiab ruaj khov muab cov khoom muaj txiaj ntsig zoo, ntxiv rau kev muab cov khoom siv thiab cov khoom siv txuag siv cov hlau muaj txiaj ntsig. Raws li cov kws tshaj lij hlau muaj txiaj ntsig, Pab Pawg yuav txuas ntxiv pab txhawb rau tib neeg lub neej yav tom ntej.
