I-TOKYO–(BUSINESS WIRE)–I-Tanaka Holdings Co., Ltd. (Ihhovisi eliyinhloko: Chiyoda-ku, eTokyo; Umqondisi omele kanye ne-CEO: Akira Tanae) namuhla imemezele ukuthi i-Tanaka Kikinzoku Kogyo KK (Ihhovisi eliyinhloko: Chiyoda-ku, eTokyo; Umqondisi omele kanye ne-CEO: Akira Tanae) yakhe imigqa yokukhiqiza ekhethekile yezingxenye zensimbi ze-Cu ezithungwe ngentambo ye-YBCO superconducting (*1) futhi isungule izinhlelo zokukhiqiza ngobuningi ezizosetshenziswa kusukela ngo-Ephreli 2015.
Ngo-Okthoba 2008, uTanaka Kikinzoku Kogyo kanye neChubu Electric Power kanye neKagoshima University bakha ndawonye ama-substrate ensimbi e-Cu aqoshiwe okuqala ngqa besebenzisa i-superconducting wire. Ukukhiqizwa kwaqala futhi amasampula asatshalaliswa kusukela ngoDisemba walowo nyaka. Le ntambo e-superconducting ithatha indawo yokusetshenziswa kwama-alloy e-Ni (ama-alloy e-nickel kanye ne-tungsten), okwakuyizinto eziyinhloko ze-substrate zensimbi eziqoshiwe, ngethusi elingabizi kakhulu neliphezulu (*2), ngaleyo ndlela kunciphisa izindleko ngaphezu kuka-50%. Enye yobuthakathaka bethusi ukuthambekela kwayo ekushisweni yi-oxidation, okungabangela ukuthi ifilimu encane (i-superconducting wire noma i-oxide buffer layer) eyakhiwe ku-substrate ihlukane. Kodwa-ke, ukuqondiswa kanye nobushelelezi bomphezulu kuyanda ngokusebenzisa isisombululo esikhethekile se-nickel plating esiqukethe i-palladium njengengqimba yokuvimbela insimbi ye-oxygen, okuthuthukisa ukuzinza kokubekwa kwefilimu encane ku-substrate.
Kusukela amasampula e-Cu substrates athunyelwe okokuqala, iTanaka Kikinzoku Kogyo iqhubekile nokwenza ucwaningo ukuqinisekisa ukuqina kokufakwa. Ukukhiqizwa kwe-substrates ezinde sekuvele kwenzeka ngokusebenzisa izimo zemishini. Ukuze kuphendulwe isidingo sasekhaya nesamazwe ngamazwe ngokushesha, kwakhiwa umugqa wokukhiqiza okhethekile esitshalweni esiphethwe yinkampani ngo-Ephreli 2015. Kulindeleke ukuthi lobu buchwepheshe buzosetshenziswa kweminye imikhakha eyahlukene esikhathini esizayo okuhlanganisa izintambo zikagesi ezikude nezinamandla aphezulu, iMagnetic Resonance Imaging (MRI) kanye neNuclear Magnetic Resonance (NMR), ezidinga amasimu amakhulu kazibuthe, kanye nama-motor emikhumbi emikhulu. ITanaka Kikinzoku Kogyo ihlose ukufeza ukuthengiswa kwaminyaka yonke kwama-yen ayizigidi eziyizinkulungwane eziyi-1.2 ngonyaka ka-2020.
Ukuboniswa kwesampula kwalesi sisekelo kusetshenziswa ucingo olusebenzisa i-superconducting kwaboniswa ngempumelelo ku-2nd High-function Metal Expo phakathi kuka-Ephreli 8 no-Ephreli 10, 2015, eTokyo Big Sight.
*1 Ucingo lwe-YBCO superconducting Izinto zokuphatha amandla kagesi ezicutshungulwa ukuze zisetshenziswe njengocingo olungenawo nhlobo ukumelana nogesi. Lwakhiwe nge-yttrium, i-barium, ithusi kanye nomoya-mpilo.
*2 UkuqondiswaLokhu kubonisa izinga lokufana ekuqondisweni kwamakristalu. Izinga elikhulu lokuqhutshwa kwamandla amakhulu lingatholakala ngokuhlela amakristalu ngezikhathi ezijwayelekile.
Izintambo eziqhuba i-superconducting zinesici sokukhiqiza amasimu anamandla kazibuthe uma zigoqiwe. Zihlukaniswa ngokwezinga lokushisa elibucayi (izinga lokushisa lapho zithola khona i-superconductivity). Izinhlobo ezimbili “intambo eqhuba i-superconducting ephezulu,” egcina i-superconductivity ku--196°c noma ngaphansi, kanye “nentambo eqhuba i-superconducting ephezulu,” egcina i-superconductivity ku--250°c noma ngaphansi. Uma kuqhathaniswa nentambo eqhuba i-superconducting ephezulu, esevele isetshenziswa kwi-MRI, i-NMR, izimoto ezihamba ngomugqa nokuningi, intambo eqhuba i-superconducting ephezulu inobuningi bamanje obubucayi (usayizi wamanje kagesi), yehlisa izindleko ngokusebenzisa i-nitrogen ewuketshezi ukupholisa, futhi inciphisa ukuthambekela emiphumeleni yamasimu kazibuthe angaphandle, ngakho-ke ukuthuthukiswa kwentambo eqhuba i-superconducting ephezulu kuyakhuthazwa okwamanje.
Kukhona izintambo ezisebenzisa i-bismuth (ezibizwa ngokuthi “ezisekelwe ku-bi” ngezansi) kanye nezintambo ezisebenzisa i-yttrium (ezibizwa ngokuthi “ezisekelwe ku-Y” ngezansi) ezisebenzisa izinga lokushisa eliphezulu. Ezisebenzisa i-bi zigcwaliswa ngepayipi lesiliva elicutshungulwa ukuze lisetshenziswe njengentambo, kuyilapho ezisebenzisa i-Y zifakwa endaweni engaphansi kwesakhiwo ngefomethi yetheyiphu enamakristalu aqondile ukuze zisetshenziswe njengentambo. Ezisebenzisa i-Y kulindeleke ukuthi zibe yisizukulwane esilandelayo sezintambo ezisebenzisa i-superconducting njengoba zinobukhulu bamanje obuphezulu kakhulu, izici zamandla kazibuthe ezinamandla, futhi izindleko zezinto zingancishiswa ngokunciphisa inani lesiliva elisetshenziswayo.
Izici ze-substrates ze-superconducting wire ezisekelwe ku-Y kanye nentuthuko yobuchwepheshe eTanaka Kikinzoku Kogyo
Ngokuphathelene ne-substrates ze-superconducting wire ezisekelwe ku-Y, senza i-R&D “ye-IBAD substrates” kanye “ne-textured substrates.” Izici ze-Superconductivity ziyanda ngokuhlela amakristalu ensimbi ngezikhathi ezijwayelekile, ngakho-ke ukucutshungulwa kokuqondiswa kwensimbi kumele kucutshungulwe kungqimba ngayinye eyakha itheyiphu. Kuma-substrates e-IBAD, ungqimba lwefilimu oluncane lwe-oxide luqondiswa ohlangothini oluthile kunsimbi enamandla aphezulu angaqondiswanga, kanti ungqimba lwe-superconducting lubekwa ku-substrate kusetshenziswa i-laser, edala izinto ze-substrate eziqinile, kodwa futhi iphakamisa inkinga yezindleko zemishini nezinto zokwakha. Yingakho uTanaka Kikinzoku Kogyo egxile kuma-textured substrates. Izindleko zincishiswa ngokusebenzisa ithusi eliqondiswe phezulu njengezinto ze-substrate, okwandisa namandla omshini uma kuhlanganiswa nongqimba lwezinto zokuqinisa kusetshenziswa ubuchwepheshe be-clad obungathinti ukuqondiswa.
Yasungulwa ngo-1885, i-Tanaka Precious Metals yakhe uhla oluhlukahlukene lwemisebenzi yebhizinisi egxile ekusetshenzisweni kwezinsimbi eziyigugu.
