Tungsten tau pom nyob rau hauv 1781 los ntawm Swedish chemist Schoeller. Los ntawm thaum pib ntawm lub xyoo pua 20th, vim yog kev txhim kho ntawm ntau daim ntawv thov, xws li thawj qhov kev nthuav qhia ntawm high-speed steel nrog tungsten raws li cov khoom siv alloying thiab lub teeb teeb ua los ntawm tungsten hlau ntawm Paris World's Exhibition xyoo 1900, thiab kev txhim kho ntawm tungsten carbide-raws li sintered cemented carbide nyob rau hauv 1927-1928, tungsten metallurgical kev lag luam pib yug thiab tsim.
Txhawm rau kom ua tau raws li qhov yuav tsum tau ua kom zoo ntawm cov neeg siv khoom tungsten, txo cov nqi thiab txo cov pa phem ib puag ncig, tungsten metallurgy thev naus laus zis tau ua tiav zoo, thiab cov thev naus laus zis tshiab tau hloov tag nrho cov tsoos thev naus laus zis. Nws yog feem ntau yog reflected nyob rau hauv cov nram qab no yam:
Nyob rau hauv cov nqe lus ntawm decomposition ntawm tungsten ntxhia raw cov ntaub ntawv, lub thaum ntxov industrialized dej qab zib nias ua noj txoj kev tau tsim rau hauv ib tug dav siv technology uas tsis tau tsuas yog cov txheej txheem scheelite concentrate, qis-qib scheelite nruab nrab-ore, tab sis kuj dub-rau-dawb tungsten tov ore. , thiab raws li kev tshawb fawb theoretical, NaOH (sodium hydroxide) decomposition txoj kev tau tsim los ntawm cov uas tsis muaj calcium wolframite mloog mus rau ib tug dav siv technology uas yuav kho ntau yam tungsten ntxhia raw cov ntaub ntawv, xws li scheelite concentrate thiab refractory tungsten nruab nrab-ore. Tau kawg, nrog rau txoj kev loj hlob, cov txheej txheem ib txwm muaj kev ua haujlwm tsawg thiab muaj kuab paug ib puag ncig, xws li NaOH melting, dej qab zib sintering, thiab hydrochloric acid decomposition, tau raug txiav tawm. Nyob rau tib lub sijhawm, nws kuj txo cov kev xav tau rau kev ua cov ntxhia thiab txhim kho cov peev txheej siv nyiaj ntau.
Nyob rau hauv kev npaj ntawm ntshiab tungsten tebchaw, muaj zog alkaline anion pauv purification thiab transformation txheej txheem ntawm crude Na2WO4 tov, raws li zoo raws li cov yam ntxwv ntawm cov txheej txheem luv luv, tsis tshua muaj nqi thiab cov khoom zoo, tau hloov cov classic magnesium ntsev purification-tseem siv tshuaj transformation txheej txheem. mus rau qhov loj. Kev ua kom huv thiab hloov pauv ntawm quaternary ammonium ntsev extraction txoj kev sib raug rau nws tau pib txav los ntawm kev tshawb fawb thiab kev loj hlob mus rau industrialization, nthuav qhia qhov kev cia siab zoo. Txoj kev xaiv nag lossis daus tau tsim tiav thiab dav siv los tshem tawm molybdenum, tin, antimony, arsenic thiab lwm yam kev ua kom huv thiab tsis huv los ntawm cov tshuaj tungstate, uas tau txhim kho cov purity ntawm tungsten cov khoom thiab kev hloov pauv ntawm tungsten metallurgical txheej txheem rau raw. cov ntaub ntawv.
Nyob rau hauv kev npaj ntawm tungsten hlau hmoov, nyob rau hauv lub 70s ntawm lub xyoo pua 20th, lub advanced xiav tungsten hydrogen txo txoj kev hloov lub daj tungsten hydrogen txo txoj kev, thiab nyob rau hauv lub kawg ntawm lub xyoo pua 20th, cov ntshav tungsten hydrogen txo txoj kev ntxiv rau xiav. tungsten hydrogen txo txoj kev, kom lub cev muaj zog ntawm tungsten hmoov tswj tau mus txog qib siab dua, thiab ntxiv txhim kho qhov zoo ntawm tungsten hmoov.
Nyob rau tib lub sijhawm, kev tshawb fawb thiab kev loj hlob ntawm ntau yam thev naus laus zis rau kev kho mob ntawm tungsten metallurgical theem nrab cov peev txheej tau txhim kho kev siv cov khoom siv tungsten theem nrab hauv cov ntsiab lus ntawm cov txheej txheem thiab cov nqi rov ua dua.
Kev tshawb fawb thiab thev naus laus zis yog lub zog tseem ceeb, thiab cov peev txheej tungsten, yog cov khoom siv tseem ceeb, yog cov peev txheej tseem ceeb hauv ntiaj teb, uas yuav tsum tau rov ua dua tshiab.
