Ib nyuag Keeb Kwm Ntawm Molybdenum Discovery

Txawm hais tias molybdenum tau pom nyob rau hauv lub xyoo pua 18th, nws twb tau siv ua ntej nws nrhiav pom, piv txwv li, nyob rau hauv lub xyoo pua 14th, hlau uas muaj molybdenum tau siv los ua sabers nyob rau hauv Nyiv. Nyob rau hauv lub xyoo pua 16th, molybdenum pyroxene, vim hais tias ntawm nws zoo sib xws nyob rau hauv tsos thiab cov khoom siv lead ua, galena thiab graphite, yog siv raws li graphite, thiab Europeans nyob rau hauv lub sij hawm collectively xa mus rau cov ores li "molybdenite".
Xyoo 1754, Swedish chemist BengtAnderssonQvist kuaj molybdenite thiab pom tias nws tsis muaj txhuas, yog li nws ntseeg tias molybdenite thiab galena tsis yog tib yam khoom.

Xyoo 1778, Swedish chemist Scherer pom tias nitric acid tsis hnov ​​​​mob nrog graphite, tab sis reacted nrog molybdenite kom tau ib tug dawb hmoov, uas yog boiled nrog ib tug alkali tov thiab crystallized rau hauv ntsev. Nws xav tias cov hmoov dawb no yog cov hlau oxide, tov nrog charcoal tom qab muaj zog cua sov, thiab tsis tau cov hlau, tab sis thaum nws tau rhuab nrog sulfur ua ke tab sis tau txais cov qub molybdenite, yog li nws xav tias molybdenite yuav tsum yog ib hom tsis paub. lub ntsiab ntawm cov mineral.
Raws li Scherer qhov kev tshoov siab, xyoo 1781, Swede Järm tau siv "txoj kev txo cov pa roj carbon" los cais cov hlau tshiab los ntawm cov hmoov dawb no, thiab hu ua cov hlau "Molybdenum".
