Kev xaiv cov ntaub ntawv muaj kev txiav txim siab ntawm lub peev xwm emission thiab lub neej ntawm rab phom electron.Filament yuav tsum tau ua los ntawm cov ntsiab lus melting siab thiab cov khoom siv siab, feem ntau yog ua los ntawm tungsten hlau.Tom qab dhau los ntawm qhov muaj zog tam sim no, cov filament yog rhuab mus rau ntau tshaj 1000 degrees.
Lub cathode yuav tsum tau ua los ntawm cov khoom siv ua haujlwm tsawg.Lub sab nrauv electrons ntawm cov atoms ntawm lub cathode nto, tom qab tau zoo siab los ntawm ib tug npaum li cas ntawm tshav kub los yog hluav taws xob zog, yuav detach lub nucleus thiab ua dawb electrons.Tungsten hlau yog xaiv raws li cov khoom siv, thiab nws txoj haujlwm ua haujlwm yog 4.55 electron volts.
Thaum ua haujlwm kub yog 2500K, J = 0.5A / cm².Lub melting point ntawm tungsten hlau yog 3655 K. Thaum ua hauj lwm kub yog 2750 K. evaporation tus nqi yog 0.0043mg / cm·s, thiab corrosion kuj ntawm tungsten hlau yog muaj zog.
