Hauj lwm lawm
Tungsten yog greyish-dawb lustrous hlau; nws yog khoom ntawm chav tsev kub. Nws muaj qhov siab tshaj plaws melting point, qis tshaj vapor siab ntawm qhov kub siab tshaj 1650 degree, lub zog siab tshaj plaws, thiab lub siab tshaj plaws hardness ntawm tag nrho cov ntshiab hlau thiab alloys. Ntshiab tungsten hlau yog thawj zaug cais los ntawm ob tug Mev (de Elhujar) cov kwv tij nyob rau hauv 1783. Lo lus "tungsten" los ntawm ib tug Swedish "tig sten", txhais tau tias "hnyav pob zeb." Tungsten lub cim tshuaj "W" los ntawm lub ntsiab lub npe, wolfram, uas yog muab los ntawm wolframite, cov ntxhia hauv lub caij tau pom nyob rau hauv.
Khoom Description
Feem ntau siv rau cov ntshiab tungsten filaments
Teeb pom kev zoo. Tungsten tau dav siv los ua ib qho filament nyob rau hauv cov tsoos incandescent teeb qhov muag teev. Vim lawv lub zog tsis tshua muaj zog, kev tsim hluav taws xob siab thiab lub neej luv luv, cov qij no tau maj mam hloov los ntawm fluorescent thiab tsis ntev los no los ntawm LED teeb.
Cov khoom siv hluav taws xob thiab cov khoom siv kub kub. Vim nws qhov siab melting point thiab lub zog, tungsten thiab nws cov alloys yog siv nyob rau hauv ib tug ntau yam ntawm high-kub daim ntaub ntawv, xws li arc vuam electrodes, cua sov ntsiab thiab shields nyob rau hauv high-temperature nqus tsev vacuum furnaces, thiab turbine hniav nyob rau hauv generators thiab aircraft engine. .
X-ray lub hom phiaj. Tungsten yog cov khoom siv siv ntau tshaj plaws hauv X-ray txheej txheem. Tungsten tus lej atomic siab nce qhov kev siv ntawm X-rays ntawm qee qhov voltages thiab tam sim no. Tungsten lub siab melting point kuj ua rau X-ray anode dawb-kub.
Kev tiv thaiv hluav taws xob. Tungsten aloy sib xyaw ua ke cov txiaj ntsig ntawm kev ua siab loj, ua rau nws cov khoom siv zoo rau kev thaiv cov hluav taws xob.
