1. Cov khoom siv hluav taws xob thiab cov khoom siv lub tshuab nqus tsev: tungsten hlau yog siv los ua cov khoom siv hluav taws xob thiab cov cua sov rau cov phom hluav taws xob kub hauv cov ntawv thov. Lawv kuj tau siv ntau hauv cov khoom siv nqus tsev xws li cov raj kub electron, electron microscopes, thiab cov khoom siv roj ionization.
2. Lub teeb pom kev zoo: Vim nws muaj peev xwm ua kom pom lub teeb ci ntawm qhov kub thiab txias thiab nws tsis kam ua kom tawg, tungsten hlau yog dav siv los ua lub teeb pom kev zoo hauv cov khoom siv hluav taws xob.
3. Resistance heater: Lub siab melting point thiab kub tsis kam ntawm tungsten hlau ua rau nws yog ib qho khoom siv zoo rau cov cua sov. Lawv feem ntau siv rau hauv tsev thiab cov khoom siv hluav taws xob cua sov xws li lub qhov cub hluav taws xob, qhov cub, thiab cov hlau.
4. Vuam thiab txiav: tungsten hlau feem ntau yog siv los ua cov khoom siv hluav taws xob hauv kev siv hluav taws xob siab thiab txiav cov txheej txheem xws li argon arc vuam, laser txiav, thiab electron beam vuam. Nws qhov siab melting point thiab corrosion kuj ua rau nws yog ib qho kev xaiv zoo tshaj plaws rau kev pib arc thiab tso tawm tam sim no hauv cov txheej txheem no.
5. Chemical reactors: Hauv qee cov tshuaj reactors, tungsten xov hlau yog siv los ua catalysts thiab txhawb cov ntaub ntawv los txhim kho cov tshuaj tiv thaiv thiab kev ruaj ntseg.
Ntxiv rau cov ntawv thov saum toj no, tungsten hlau kuj tau siv dav hauv kev lag luam textile, aerospace, kev lag luam nuclear, thiab kev kho mob.
Txoj kab uas hla ntawm tungsten hlau yuav tsum tau txiav txim siab raws li qhov tshwj xeeb daim ntawv thov scenario. Feem ntau hais lus, txoj kab uas hla zoo dua, qhov hnav tsawg dua thiab rhuav tshem cov tungsten hlau yuav muaj, tab sis lub peev xwm thauj khoom thiab kev pabcuam lub neej yuav txo qis. Yog li ntawd, nws yog ib qho tsim nyog los xaiv raws li cov kev xav tau tshwj xeeb.
Cov khoom siv ntawm tungsten hlau muaj qhov cuam tshuam loj rau nws daim ntawv thov. Ntshiab tungsten muaj qhov kub thiab txias zog zoo dua li tungsten alloy. Yog li ntawd, nyob rau hauv lub sij hawm uas siab purity thiab siab corrosion kuj yuav tsum tau, nws yog pom zoo kom xaiv cov ntshiab tungsten hlau; Tungsten alloy muaj lub zog zoo dua thiab ductility, ua rau nws haum rau qee yam kev siv tshwj xeeb xws li lub tshuab hluav taws xob, lub tshuab nqus tsev, thiab lwm yam.
Lub sijhawm melting ntawm tungsten hlau rhuab hauv lub tshuab nqus tsev yog nyob ntawm tus nqi evaporation ntawm tungsten. Thiab cov cua kub ntawm tungsten hlau hauv huab cua tsim tungsten oxide. Lub melting point ntawm tungsten yog 3410 degrees. Lub melting point ntawm tungsten oxide, WO3, yog 1400-1600 degrees. Raws li kev ua haujlwm ib txwm muaj, qhov kub ntawm cov filament yog nyob ib ncig ntawm 2500 degrees, thiab WO3 sai vaporizes ntawm qhov kub thiab txias, ua rau cov filament sai yaj hauv huab cua.
