Hlau tantalum atomic tooj yog 73 thiab nws cov cim atomic yog Ta. Nws cov ntsiab lus melting yog 5,462.6 F thiab nws cov ntsiab lus kub yog 9,856.4 F.
Lub npe tom qab Tantalus, Greek mythological ua cim, hlau tantalum tau pom thawj zaug hauv xyoo 1802. Yog tias koj yuav tsum nrhiav cov hlau tantalum, koj yuav pom tias nws tshwm sim nyob rau hauv cov ntxhia columbite-tantalite uas muaj nyob hauv ntau lub tebchaws, suav nrog. Canada, Australia, Brazil, Thaib teb thiab ib feem ntawm Africa.
Kev siv hlau tantalum
Yog li dab tsi yog hlau tantalum siv rau? Nws yog feem ntau siv rau electrolytic capacitors thiab lub tshuab nqus tsev qhov chaw. Koj tuaj yeem pom nws hauv cov txheej txheem tshuaj lom neeg nrog rau cov tshuab hluav taws xob nuclear thiab cov dav hlau thiab cov foob pob hluav taws. Vim tias nws tiv taus cov kua hauv lub cev, hlau tantalum yog siv los ua cov khoom siv phais. Hlau tantalum oxide tuaj yeem siv los ua ib lub iav tshwj xeeb (nrog rau qhov ntsuas siab ntawm refraction) uas koj tuaj yeem pom hauv qee lub koob yees duab lo ntsiab muag. Hlau tantalum muaj ntau yam siv.
Kev lag luam uas nyob ntawm cov hlau tantalum
Hlau tantalum yog siv nyob rau hauv ntau industries, nrog rau ib tug tshwj xeeb tseem ceeb nyob rau hauv lub electronics kev lag luam. Nws yog cov hlau ruaj khov nrog cov qib siab ntawm corrosion kuj. Qhov tseeb, nws yog ib feem ntawm cov chav kawm ntawm cov hlau hu ua refractory hlau, raws li tau hais los ntawm kev muaj zog tiv thaiv tshav kub thiab hnav - thiab qhov no yog ua tsaug rau nws cov ntsiab lus melting siab heev.
Dab tsi Mineral Yog Hlau Tantalum Ua Los Ntawm?
Ntuj tantalum muaj ob lub isotopes ruaj khov: 180mTa ({12}}.012%) thiab 181Ta (99.988%). 180mTa (m qhia txog lub xeev metastable) tau kwv yees kom lwj hauv peb txoj kev: isomeric hloov mus rau hauv av xeev ntawm 180Ta, beta lwj mus rau 180W, lossis electron capture rau 180Hf. Txawm li cas los xij, hluav taws xob hluav taws xob ntawm cov isomer nuclear no tsis tau pom dua, thiab tsuas yog qis dua ntawm nws ib nrab-lub neej ntawm 2.0 × 1016 xyoo tau teeb tsa.Lub xeev hauv av ntawm 180Ta muaj ib nrab ntawm lub neej tsuas yog 8 teev. 180mTa yog tib qhov tshwm sim ntawm nuclear isomer (tsis suav nrog radiogenic thiab cosmogenic luv luv nuclides). Nws tseem yog qhov tsawg tshaj plaws primordial isotope nyob rau hauv lub ntiaj teb no, coj mus rau hauv tus account lub ntsiab abundance ntawm tantalum thiab isotopic abundance ntawm 180mTa nyob rau hauv lub ntuj sib tov ntawm isotopes (thiab dua tsis suav nrog radiogenic thiab cosmogenic luv luv nuclides).
Hlau tantalum tau raug soj ntsuam theoretically raws li "salting" khoom rau nuclear riam phom (cobalt yog cov zoo-paub hypothetical salting khoom). Lub plhaub sab nraud ntawm 181Ta yuav raug irradiated los ntawm lub zog siab zog neutron flux los ntawm kev xav txog kev tawg riam phom nuclear. Qhov no yuav kis tau cov hlau tantalum mus rau hauv lub xov tooj cua isotope 182Ta, uas muaj ib nrab-lub neej ntawm 114.4 hnub thiab tsim gamma rays nrog kwv yees li 1.12 lab electron-volts (MeV) ntawm lub zog apiece, uas yuav ua rau kom cov xov tooj cua ntawm lub nuclear fallout los ntawm. tawg tau ob peb lub hlis. Xws li riam phom "salted" yeej tsis tau tsim lossis sim, kom deb li deb tau paub rau pej xeem, thiab yeej tsis tau siv los ua riam phom.
Hlau tantalum tuaj yeem siv los ua cov khoom siv rau cov kab hluav taws xob nrawm rau kev tsim cov isotopes luv luv xws li 8Li, 80Rb, thiab 160Yb.
