Koj Paub Ntau npaum li cas txog Tantalum?
Tantalum yog lub thib peb refractory hlau tom qab tungsten thiab rhenium. Tantalum muaj cov khoom zoo heev xws li cov ntsiab lus siab melting, tsis tshua muaj vapor siab, ua haujlwm txias ua haujlwm zoo, muaj tshuaj lom neeg ruaj khov, muaj zog tiv taus cov kua hlau corrosion, thiab loj dielectric tas li ntawm oxide zaj duab xis. Nws muaj cov ntawv thov tseem ceeb hauv kev siv thev naus laus zis xws li atomic zog, superconducting technology, automotive electronics, aerospace, kev kho mob thiab kev tshawb fawb tshawb fawb. Tam sim no, qhov tseem ceeb ntawm kev siv tantalum yog tantalum capacitors.
Yuav nrhiav tau tantalum li cas
Nyob rau hauv nruab nrab -17th caug xyoo, ib tug hnyav dub ntxhia nyob rau hauv North America raug xa mus rau lub tsev khaws puav pheej British rau kev nyab xeeb. Tom qab kwv yees li 150 xyoo, txog rau xyoo 1801, British chemist Charles Hatchet tau txais txoj haujlwm los tshuaj xyuas cov ore no hauv British Tsev khaws puav pheej, thiab nrhiav tau ib qho tshiab los ntawm nws thiab muab nws lub npe hu ua columbium (tom qab hloov nws lub npe). niobium).
Nyob rau hauv 1802, thaum Swedish chemist Anders Gustav Ekberg soj ntsuam ib tug ntxhia (niobium-tantalum ore) nyob rau hauv Scandinavia, tom qab ua lawv cov kua qaub rau hauv ib tug fluorinated ob ntsev ntsev, Tom qab recrystallization, ib tug tshiab lub sij hawm nrhiav tau, uas nws hu ua Tantalum-tantalum nyob rau hauv kev siv. Lub npe ntawm Tantalus, tus tub ntawm tus vajtswv Zeus nyob rau hauv Greek mythology.
Txawm hais tias tantalum tau pom nyob rau hauv lub xyoo pua puv 19, cov hlau tantalum tsis tau tsim kom txog rau thaum xyoo 1903, thiab kev tsim khoom ntawm tantalum pib nyob rau hauv 1922. Yog li ntawd, txoj kev loj hlob ntawm tantalum kev lag luam pib nyob rau hauv 1920s, thiab Suav tantalum kev lag luam pib nyob rau hauv lub xyoo pua puv 19. Xyoo 1956.
Tebchaws Asmeskas yog thawj tus tsim tantalum. Xyoo 1922, nws tau pib tsim cov hlau tantalum ntawm kev lag luam. Nyiv thiab lwm cov peev nyiaj txiag .. ob qho tib si tsim kev lag luam tantalum los ntawm lig 1950s lossis thaum ntxov 1960s. Tom qab ntau xyoo ntawm txoj kev loj hlob, kev tsim khoom ntawm tantalum tau mus txog qib siab heev. Txij li thaum xyoo 1990, cov khoom lag luam loj loj tantalum tau suav nrog peb pawg loj: Cabot Group hauv Tebchaws Meskas, HCST Group hauv Tebchaws Yelemees, thiab Ningxia Dongfang Tantalum Kev Lag Luam Co., Ltd. Cov khoom tantalum uas tsim los ntawm peb pawg no suav txog 80 feem pua ntawm tag nrho. feem pua saum toj no. Cov khoom, txheej txheem thev naus laus zis thiab khoom siv ntawm kev lag luam txawv teb chaws tantalum feem ntau yog nyob rau theem siab, uas ua tau raws li cov kev xav tau ntawm kev loj hlob sai ntawm kev tshawb fawb thiab thev naus laus zis.
Kev txhim kho ntawm Tuam Tshoj txoj kev lag luam tantalum ntsib qee yam teeb meem. Yog tias cov ntaub ntawv raw khoom tsis txaus, cov peev txheej khaws cia yog tsawg. Cov ntaub ntawv pov thawj tantalum hauv Suav teb yog tus cwj pwm los ntawm cov hlab ntsha tawg, cov ntxhia hauv cov ntxhia nyuaj, qis Ta2O5 qib hauv cov ore raw, nplua cov ntxhia hauv cov granularity, thiab qee qhov kev lag luam, yog li nws nyuaj rau tsim cov mines loj. Txawm hais tias loj-scale tantalum-niobium mines kuj tau pom nyob rau hauv xyoo tas los no, cov ncauj lus kom ntxaws geological tej yam kev mob, ntxhia tej yam kev mob thiab kev ntsuam xyuas nyiaj txiag tsis meej. Yog li ntawd, cov khoom ntawm thawj tantalum raw cov ntaub ntawv nyob rau hauv Tuam Tshoj yog heev teeb meem.
Tuam Tshoj txoj kev lag luam tantalum tseem tab tom ntsib nrog lwm qhov teeb meem, uas yog, tsis muaj cov khoom lag luam loj hlob muaj peev xwm. Nws yog undeniable hais tias txawm hais tias Tuam Tshoj lub tantalum kev lag luam tshuab thiab cov cuab yeej tsim tau zoo heev, thiab nws muaj peev xwm tsim tau ib tug ntau yam ntawm tantalum khoom nyob rau hauv batches, muaj ntau tshaj peev xwm nyob rau hauv nruab nrab thiab qis qib. Cov khoom lag luam xws li cov ntim tshwj xeeb siab siab tantalum hmoov thiab tantalum rau semiconductors Qhov kev txaj muag ntawm cov peev txheej tsis txaus xws li lub hom phiaj yog qhov nyuaj rau thim rov qab. Vim tias qhov me me ntawm kev lag luam high-tech hauv tsev thiab tsis txaus tsav tsheb, kev tsim cov khoom siv high-tech hauv Suav teb kev lag luam tantalum tau cuam tshuam. Los ntawm kev xav txog kev lag luam, kev txhim kho ntawm kev lag luam tantalum tsis muaj kev taw qhia thiab kev tswj hwm. Nyob rau hauv xyoo tas los no, tantalum smelting thiab ua lag luam tau loj hlob sai los ntawm 5 thaum pib mus rau 20, thiab duplication ntawm kev tsim kho yog heev loj, thiab ntau lawm muaj peev xwm tseem ceeb heev.
Nyob rau hauv lub xyoo ntawm tantalum lag luam, Suav tantalum tuam txhab uas muag tau txhim kho lawv cov craftsmanship thiab cov cuab yeej, thiab txhim kho cov nplai, ntau yam thiab zoo ntawm lawv cov khoom, thiab tau nkag mus rau hauv qeb ntawm cov loj tshaj plaws lub teb chaws nyob rau hauv ntau lawm thiab daim ntawv thov ntawm tantalum kev lag luam. Ntev npaum li qhov teeb meem ntawm cov khoom siv raw, kev lag luam ntawm cov khoom siv high-tech thiab cov teeb meem ntawm kev lag luam restructuring yog ntxiv daws, Tuam Tshoj txoj kev lag luam tantalum yuav twv yuav raug hu nkag mus rau hauv cov teb chaws muaj zog.
