Tantalum Hlau
Tantalum yog tshuaj lom neeg zoo li niobium, vim tias ob qho tib si muaj cov khoom siv hluav taws xob zoo sib xws thiab, vim yog lanthanide contraction, lub vojvoog ntawm tantalum ion yuav luag zoo ib yam li ntawm niobium. Tantalum feem ntau yog nyob rau hauv {{0}} oxidation xeev nyob rau hauv nws cov tebchaw; qis oxidation xeev tau npaj, tshwj xeeb tshaj yog +2 rau +4. Tantalum tebchaw yog qhov tsis tseem ceeb hauv kev lag luam, txawm hais tias carbide TaC yog siv hauv cov cuab yeej carbide rau kev ua cov hlau nyuaj. Yuav luag txhua qhov tshwm sim tantalum yog ib qho isotope ruaj khov ntawm tantalum -181. Txawm li cas los xij, ib feem me me, 0.012%, tantalum-180, muaj cov khoom txawv txav pom hauv lub xeev zoo siab. Lub xeev zoo siab ib nrab-lub neej ntawm tantalum-180 tshaj 1.2 x 10 15 xyoo; lub neej ib nrab ntawm lub xeev hauv av (lub xeev lub zog qis tshaj) tsuas yog 8.154 teev.
Hauj lwm lawm
Tantalum yog cov khoom siv tshuaj nrog lub cim Ta thiab tus lej atomic 73.Tantalum yav tas los hu ua tantalum, muaj npe tom qab Greek mythological cim Tantalus. Tantalum yog ib qho nyuaj heev, ductile, lustrous xiav-grey hloov pauv hlau uas tiv taus corrosion heev. Nws yog cov hlau refractory thiab yog dav siv los ua ib feem ntawm cov alloys muaj zog nrog cov ntsiab lus siab melting. Nws belongs rau pawg 5 cov ntsiab lus nrog vanadium thiab niobium, thiab ib txwm tshwm sim hauv cov khoom siv geological ua ke nrog niobium, uas yog cov tshuaj zoo sib xws, thiab pom muaj nyob hauv cov zaub mov xws li tantalite, columbite thiab coltan.
Khoom Description
Tantalum cov tshuaj inertness thiab siab melting point ua rau nws yog ib qho tseem ceeb cov ntaub ntawv rau kev kuaj thiab industrial cov khoom xws li cov tshuaj tiv thaiv hlab ntsha thiab lub tshuab nqus tsev vacuum furnaces. Nws kuj tseem siv rau hauv tantalum capacitors rau cov khoom siv hluav taws xob xws li khoos phis tawj. Tantalum tau lees paub tias yog lub hauv paus thev naus laus zis los ntawm European Commission.
