Tantalumyog lub thib peb refractory hlau tom qabtungstenthiabrhenium. 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 siab dielectric tas li ntawm nto oxide zaj duab xis. Nws muaj cov ntawv thov tseem ceeb hauv kev ua haujlwm siab xws li electronics, metallurgy, steel, chemical kev lag luam, hard alloys, atomic zog, superconducting technology, automotive electronics, aerospace, kev kho mob thiab kev noj qab haus huv, 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-7th 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 Hatchett tau txais qhov kev tshuaj ntsuam xyuas ntawm cov pob zeb no los ntawm British Tsev khaws puav pheej thiab nrhiav tau lub ntsiab lus tshiab los ntawm nws, naming nws Columbium (tom qab hloov npe hu ua Niobium). Xyoo 1802, Swedish chemist Anders Gustav Eckberg tau tshawb pom lub ntsiab lus tshiab los ntawm kev tshuaj xyuas cov ntxhia (niobium tantalum ore) hauv Scandinavian Peninsula, uas muaj nws cov kua qaub hloov mus rau hauv fluoride ob lub ntsev thiab tom qab ntawd recrystallized. Nws muab lub npe no Tantalum tom qab Tantalus, tus tub ntawm Zeus hauv Greek mythology.
Xyoo 1864, Christian William Blomstrang, Henry Edin St. Clair Deville, thiab Louis Joseph Trost tau ua pov thawj tseeb tias tantalum thiab niobium yog ob yam tshuaj sib txawv thiab txiav txim siab cov qauv tshuaj rau qee qhov sib txuas. Nyob rau hauv tib lub xyoo, Demalinia rhuab tantalum chloride nyob rau hauv ib puag ncig hydrogen thiab tsim tantalum hlau thawj zaug los ntawm kev txo cov tshuaj tiv thaiv. Werner Bolton thawj zaug ua cov hlau ntshiab tantalum hauv xyoo 1903. Cov kws tshawb fawb yog thawj zaug siv cov txheej txheem crystallization los rho tantalum los ntawm niobium. Txoj kev no tau tshawb pom los ntawm Demalinia hauv xyoo 1866. Txoj kev siv los ntawm cov kws tshawb fawb niaj hnub no yog cov kuab tshuaj rho tawm ntawm cov tshuaj tantalum uas muaj fluoride.
Kev txhim kho keeb kwm ntawm tantalum kev lag luam
Txawm hais tias tantalum tau pom nyob rau xyoo 19th thaum ntxov, nws tsis yog txog xyoo 1903 uas cov hlau tantalum tau tsim, thiab kev tsim khoom ntawm tantalum pib nyob rau hauv 1922. Yog li ntawd, kev loj hlob ntawm lub ntiaj teb no tantalum kev lag luam pib nyob rau hauv lub 1920s, thiab Tuam Tshoj txoj kev lag luam tantalum pib nyob rau hauv 1922. Xyoo 1956. Tebchaws Meskas yog thawj lub tebchaws hauv ntiaj teb uas pib tsim cov tantalum, thiab pib tsim cov khoom siv hlau tantalum hauv xyoo 1922. Nyiv thiab lwm lub tebchaws capitalist pib tsim kev lag luam tantalum nyob rau xyoo 1950s lossis thaum ntxov 1960s. Tom qab ntau xyoo ntawm txoj kev loj hlob, lub ntiaj teb no tantalum kev lag luam ntau lawm tau mus txog ib tug txiav txim siab theem. Txij li thaum xyoo 1990, muaj peb lub tuam txhab loj tantalum ntau lawm: Cabot Group los ntawm Tebchaws Meskas, HCST Group los ntawm Lub Tebchaws Yelemees, thiab Ningxia Oriental Tantalum Industry Co., Ltd. los ntawm Tuam Tshoj. Peb pawg no tsim ntau tshaj 80% ntawm lub ntiaj teb tag nrho cov khoom tantalum. Cov khoom, txheej txheem thev naus laus zis, thiab cov cuab yeej siv qib ntawm kev lag luam tantalum txawv teb chaws feem ntau yog siab, uas ua tau raws li qhov xav tau ntawm kev loj hlob sai ntawm ntiaj teb kev tshawb fawb thiab thev naus laus zis.
Kev lag luam tantalum hauv Suav teb tau pib hauv xyoo 1960. Nyob rau hauv cov theem thaum ntxov ntawm tantalum smelting thiab ua nyob rau hauv Tuam Tshoj, qhov luaj li cas ntawm ntau lawm, qib technologies, qib khoom, thiab zoo nyob deb ntawm cov teb chaws tsim. Txij li thaum xyoo 1990, tshwj xeeb tshaj yog txij li xyoo 1995, kev tsim khoom thiab kev siv tantalum hauv Suav teb tau qhia txog kev loj hlob sai. Niaj hnub no, Tuam Tshoj txoj kev lag luam tantalum tau ua tiav kev hloov pauv los ntawm me me mus rau loj, los ntawm cov tub rog mus rau pej xeem, thiab los ntawm sab hauv mus rau sab nraud, tsim lub ntiaj teb kev lag luam nkaus xwb los ntawm mining, smelting, ua rau daim ntawv thov. Cov khoom lag luam siab, nruab nrab, thiab qis kawg tau nkag mus rau hauv kev lag luam thoob ntiaj teb hauv txhua yam. Tuam Tshoj tau dhau los ua lub teb chaws thib peb muaj zog tshaj plaws hauv ntiaj teb hauv tantalum smelting thiab ua, thiab tau nkag mus rau hauv qeb ntawm lub ntiaj teb cov lag luam loj tantalum lub teb chaws.
Txoj kev loj hlob ntawm Tantalum Kev Lag Luam hauv Suav teb
Txoj kev loj hlob ntawm Tuam Tshoj txoj kev lag luam tantalum ntsib qee yam teeb meem. Yog tias muaj kev tsis txaus ntawm cov khoom siv raw thiab cov peev txheej tsis txaus. Cov yam ntxwv ntawm Tuam Tshoj cov ntaub ntawv pov thawj tantalum yog cov pob zeb hauv cov hlab ntsha tawg, cov ntxhia sib xyaw ua ke, qis Ta2O5 qib hauv cov ore qub, nplua cov ntxhia hauv cov khoom me me, thiab cov peev txheej nyiaj txiag tsawg, ua rau nws nyuaj rau tsim cov mines loj dua. Txawm hais tias loj-scale tantalumniobiumdeposits tau pom nyob rau hauv xyoo tas los no, cov ncauj lus kom ntxaws geological thiab ntxhia tej yam kev mob, nrog rau kev ntsuam xyuas nyiaj txiag, tsis meej. Yog li ntawd, muaj teeb meem tseem ceeb nrog kev muab cov khoom tseem ceeb tantalum raw khoom hauv Suav teb.
Kev lag luam tantalum hauv Suav teb tseem tab tom ntsib lwm qhov kev sib tw, uas yog qhov kev tsim kho tsis txaus ntawm cov khoom siv high-tech. Nws tsis tuaj yeem tsis lees paub tias txawm hais tias Tuam Tshoj txoj kev lag luam tantalum thev naus laus zis thiab khoom siv tau ua tiav zoo thiab muaj peev xwm tsim tau ntau yam ntawm cov khoom siv tantalum, qhov kev txaj muag ntawm overcapacity nyob rau hauv nruab nrab mus rau qis kawg thiab tsis muaj peev xwm ntau lawm rau high-end. cov khoom xws li lub peev xwm tshwj xeeb siab-voltage tantalum hmoov thiab tantalum lub hom phiaj cov ntaub ntawv rau semiconductors yog qhov nyuaj rau thim rov qab. Vim muaj kev siv tsawg thiab tsis txaus tsav tsheb ntawm kev lag luam hauv tsev high-tech, kev tsim cov khoom siv high-tech hauv Suav teb kev lag luam tantalum tau cuam tshuam. Los ntawm kev xav ntawm cov lag luam, kev tsim kho ntawm tantalum kev lag luam tsis muaj kev taw qhia thiab kev tswj hwm. Nyob rau hauv xyoo tas los no, tantalum smelting thiab ua lag luam tau tsim sai heev los ntawm thawj 5 mus rau 20, nrog loj duplication ntawm kev tsim kho thiab tseem ceeb overcapacity.
Nyob rau hauv lub xyoo ntawm kev lag luam thoob ntiaj teb, Suav tantalum tuam txhab tau txhim kho lawv cov txheej txheem thiab cov khoom siv, nce cov khoom lag luam, ntau yam, thiab zoo, thiab nkag mus rau qib ntawm kev lag luam loj tantalum ntau lawm thiab daim ntawv thov lub teb chaws. Tsuav yog peb ntxiv daws cov teeb meem ntawm cov ntaub ntawv raw, industrialization ntawm high-tech khoom, thiab kev lag luam restructuring, Tuam Tshoj lub tantalum kev lag luam yuav twv yuav raug hu nkag mus rau hauv lub ntiaj teb no powers.
