Keeb Kwm Ntawm Kev Tshawb Fawb Ntawm Tantalum

Nyob rau hauv 1802, Swedish chemist AG Ekaberg, 1767 ~ 1813, thaum soj ntsuam ib tug mineral (niobium-tantalum ore) nyob rau hauv Scandinavia, recrystallized nws tom qab tsim fluoride complex ntsev los ntawm lawv cov acids, yog li nrhiav tau ib tug tshiab lub caij, uas nws hu ua tantalum nrog rau siv. Tantalus, tus tub ntawm tus vajtswv Zeus hauv Greek mythology.
Vim tias niobium thiab tantalum zoo sib xws hauv qhov xwm txheej, lawv ib zaug xav tias yog tib lub caij; Xyoo 1809, British chemist William Hyde Wollaston piv niobium thiab tantalum oxides cais, thiab txawm hais tias nws tuaj nrog qhov sib txawv ntawm qhov sib txawv, nws suav tias lawv yog tib yam khoom.

Los ntawm 1844, German chemist Heinrich Rose, 1795 ~ 1864, tsis lees paub qhov xaus tias tantalum thiab niobium yog tib lub ntsiab lus thiab tshuaj ntsuam xyuas tias lawv yog ob lub ntsiab lus sib txawv. Nws hu ua ob lub ntsiab lus "Niobium" thiab "Pelopium" tom qab Niobe, tus ntxhais ntawm Tantalus, tus vajtswv poj niam ntawm kua muag thiab nws tus tub Pelops hauv Greek mythology.
Xyoo 1864, Christian Wilhelm Blomstrand, Henri Edin St. Clair de Ville thiab Louis Joseph Troost tau ua pov thawj tseeb tias tantalum thiab niobium yog ob yam tshuaj sib txawv thiab txiav txim siab cov qauv tshuaj rau ntau yam sib txuas.
Nyob rau hauv tib lub xyoo, de Marigny rhuab tantalum chloride nyob rau hauv ib tug hydrogen cua, yog li ua tantalum hlau thawj zaug los ntawm ib tug txo cov tshuaj tiv thaiv. Kev ua kom zoo dua qub ntawm tantalum muaj cov impurities siab, thiab thawj tantalum ntshiab yog tsim los ntawm Werner von Bolton hauv 1903.
Cov kws tshawb fawb yog thawj zaug rho tawm tantalum (potassium heptafluorotantalate) los ntawm niobium (potassium pentafluorooxyniobate monohydrate) los ntawm cov txheej txheem crystallization. Txoj kev no tau tshawb pom los ntawm de Marigny hauv xyoo 1866. Niaj hnub no, cov kws tshawb fawb siv cov kuab tshuaj tshem tawm ntawm cov tshuaj tantalum uas muaj fluoride.
