Kev Tshawb Fawb Ntawm Niobium

Charles Hatchett xyoo 1801, British chemist Charles Hatchett pom niobium nyob rau hauv ib qho piv txwv ntawm ib qho ore hauv British Tsev khaws puav pheej uas tau xa tuaj rau nws xyoo 1734 los ntawm John Winthrop ntawm Connecticut, Tebchaws Asmeskas. Txij li thaum niobium thiab tantalum zoo sib xws, thaum xub thawj nws xav tias lawv yog tib yam khoom. Txawm li cas los xij, tom qab ntawd nws tau pom tias cov tebchaw cais tawm ntawm cov ntxhia no tsis yog chromic acid tab sis oxides ntawm cov hlau tsis paub. Txij li thaum cov ntxhia los ntawm Tebchaws Meskas, qhov chaw Columbus pom nws, Hatchett hu ua ore Columbite hauv kev hwm ntawm nws keeb kwm. Qhov tseeb, vim hais tias ob lub ntsiab lus zoo sib xws, ntau tus neeg ntseeg tias lawv yog tib lub ntsiab. 1809, lwm tus kws tshawb fawb Askiv, William Hyde Wollaston, tsis raug categorized "tantalum" thiab "columbium" raws li tib yam khoom, ntseeg hais tias lawv zoo tib yam nyob rau hauv tag nrho cov respects tsuas yog ceev. Xyoo 1846, German chemist

Xyoo 1846, tus kws tshawb fawb German Heinrich Rose tau txheeb xyuas qhov sib txawv ntawm tantalum thiab coltan ores, thiab pom tias muaj lwm yam ntxiv nrog rau tantalum, uas yog ze rau tantalum, thiab hu ua lub caij tshiab no Niobium (Niobium yog muab los ntawm Greek mythological cim Niobe, raws li. Tantalum lub npe los ntawm Greek mythological cim Tantalos, thiab niobium los ntawm Greek mythological cim Tantalos. uas hais txog qhov zoo sib xws ntawm tantalum thiab niobium). Ntawm qhov zoo sib xws ntawm columbium thiab niobium los ntawm Swiss chemist Wilhelm Xyoo 1864, Swiss chemist Wilhelm Blomstrand thawj zaug tau txais niobium los ntawm kev txo cov tshuaj chloride nrog hydrogen, thiab xyoo 1951 Pawg Neeg Nomenclature ntawm International Association of Pure and Applied Chemistry (IUPAC) txiav txim siab los txais yuav. raws li lub npe official ntawm lub caij.
