Histori ea Tungsten

Tungsten ke mofuta oa ntho ea lik'hemik'hale e nang le letšoao la W mme e na le nomoro ea athomo ea 74, eo hape e ka bitsoang wolfram. Tungsten e thata ho fumanoa tlhahong e le tungsten ea mahala, 'me e lula e thehiloe e le metsoako le likarolo tse ling.

 

Tungsten e na le mefuta e 'meli ea ore. Ke scheelite le wolframite. Lebitso Wolfram le tsoa ho ea ho qetela. Lekholong la bo16 la lilemo, basebetsi ba morafong ba ile ba tlaleha hore ho na le minerale e neng e atisa ho tsamaea le tšepe ea thini. Ka lebaka la 'mala o motšo le ponahalo ea moriri oa mofuta ona oa liminerale, basebetsi ba morafong ba ile ba bitsa mofuta ona oa tšepeWolfram. Mesaletsa ena e mecha e ile ea tlalehoa ka lekhetlo la pele ho Georgius Agricolas book, De Natura Fossilium ka 1546. Scheelite e ile ea sibolloa ka 1750 naheng ea Swede. Ea pele ea e bitsang Tungsten ke Axel Frederik Cronstedt. Tungsten e entsoe ka likarolo tse peli, tung, e bolelang boima ka Seswedishe, le sten, e bolelang lejoe. Ho fihlela mathoasong a lilemo tsa bo-1780, Juan José de D´Elhuyar o fumane hore wolfram e na le lintho tse tšoanang le scheelite. Khatisong ea Juan le mor'abo, ba fa tšepe ena e ncha lebitso le lecha, wolfram. Ka mor’a moo, bo-rasaense ba eketsehileng ba ile ba hlahloba tšepe ena e ncha.

 

Ka 1847. moenjiniere e mong ea bitsoang Robert Oxland o ile a fana ka tokelo ea molao e amanang le tungsten., e leng mohato oa bohlokoa ho isa indastering.

Ka 1904, li-bulbs tsa pele tsa tungsten li ile tsa fuoa tokelo ea molao, tse ileng tsa nkela lihlahisoa tse ling sebaka ka potlako, joalo ka mabone a carbon filament a sa sebetseng hantle limmarakeng tsa mabone.

 

Lilemong tsa bo-1920, ho hlahisa setšoantšo se shoa ka thata e phahameng, e haufi le daemane, batho ba 'nile ba ntlafatsa thepa ea carbide e entsoeng ka samente.

 

Ka mor'a Ntoa ea II ea Lefatše, moruo o ntlafala haholo le ho hola. Tungsten carbide e boetse e tsebahala haholo joalo ka mofuta oa lisebelisoa tsa lisebelisoa, tse ka sebelisoang maemong a mangata.

 

Ka 1944, K C Li, Mopresidente oa Wah Chang Corporation e US, o ile a hatisa setšoantšo ho Engineering & Mining Journal se nang le sehlooho se reng: "Ho hōla ha Lilemo tse 40 tsa Sefate sa Tungsten (1904-1944)"e bonts'ang tsoelo-pele e potlakileng ea lisebelisoa tse fapaneng tsa tungsten lefapheng la metallurgy le k'hemistri.

 

Ho tloha ka nako eo, ka tsoelo-pele ea moruo le sechaba, batho ba bile le tlhokahalo e phahameng ea lisebelisoa le lisebelisoa tsa bona, e leng se khothalletsang ntlafatso e tsoelang pele ea lihlahisoa tsa tungsten carbide. Le hona joale, batho ba ntse ba etsa lipatlisiso le ho ntlafatsa tšepe ena ho fana ka katleho e ntle ea ho sebetsa le phihlelo.
