Dab tsi yog tungsten siv rau?

Dab tsi yogtungstensiv rau?

Kev siv tam sim no yog lielectrodes, cua kub ntsiab lus thiab teb emitters, thiab raws li filaments nyob rau hauv lub teeb qhov muag teev thiab cathode ray tubes. Tungsten feem ntau yog siv rau hauv cov hlau hnyav xws li cov hlau kub ceev, los ntawm cov cuab yeej txiav yog tsim. Nws kuj yog siv nyob rau hauv lub thiaj li hu ua 'superalloys' los tsim hnav-resistant coatings.

Tungsten tau dav siv nyob rau hauv filament ntawm cov laus incandescent qhov muag teev tab sis tau phased tawm nyob rau hauv ntau lub teb chaws. Qhov no yog vim lawv tsis muaj zog heev; lawv tsim kub ntau dua li lub teeb.

Tungsten muaj qhov siab tshaj plaws melting point ntawm tag nrho cov hlau thiab yog alloyed nrog rau lwm yam hlau kom nws muaj zog. Tungsten thiab nws cov alloys yog siv nyob rau hauv ntau qhov kub-kub daim ntaub ntawv, xws li arc vuam electrodes thiab cua sov ntsiab nyob rau hauv high-temperature furnaces.

Tungsten carbide yog qhov nyuaj heev thiab tseem ceeb rau kev ua hlau, mining thiab roj av kev lag luam. Nws yog tsim los ntawm kev sib xyaw tungsten hmoov thiab carbon hmoov thiab cua sov rau 2200 degree. Nws ua rau cov cuab yeej txiav thiab drilling zoo heev, suav nrog kev xyaum kho hniav tshiab "tsis mob" uas tig ntawm qhov nrawm nrawm.

Calcium tungstate thiab magnesium tungstate yog siv dav hauv cov teeb pom kev zoo fluorescent.
