Tungsten pas nrig

Tungsten yog xim hlau. Cov tshuaj lom neeg lub cim ntawm tungsten yog W, tus lej atomic muaj 74, qhov chaw nthawv thiab nws yog rau lub sijhawm thib rau (er ntev) hauv lub rooj ntu. Steel grey lossis nyiaj dawb, siab hardness, siab melting taw tes, nyob rau hauv chav tsev kub tsis yaig los ntawm huab cua; Lub ntsiab siv yog tsim cov ntaub ntawv thiab kev ceev ceev cov hlau, super tawv pwm, kuj siv nyob rau hauv cov twj siv kho mob, cov cuab yeej siv tshuaj lom neeg. Suav yog cov loj tshaj plaws tungsten cia lub teb chaws nyob hauv lub ntiaj teb.

Tungsten Qws Khoom Sab Nraud Xim Xim: Tuaj yeem muab faib ua kev zam txim tungsten pas nrig thiab polished tungsten pas nrig. Muaj ib txheej ntawm oxide nyob rau saum npoo ntawm forging tungsten pas nrig, pom xim dub; Polished tungsten pas nrig muaj ib qho nyiaj-grey nws yog xim hlau luster.
Nta:
Siab melting taw tes: lub ntsiab lus melting ntawm tungsten pas yog li 3410 degree los yog nws tuaj yeem ruaj khov rau kev siv hauv qhov chaw kub. Piv txwv li, thaum melting quartz (quartz melting point 1750 degree), nws yog haum rau xaiv cov khoom tungsten khoom raws li ntim.
Kev kub siab: Tungsten muaj qhov ntom ntom heev ntawm txog 19.2g \/ cm³ los yog 19.35g \/M³, uas txhais tau hais tias lub tungsten rods muaj lub zog zoo thiab hardness.
Zoo hluav taws xob thiab thermal delityity: tuaj yeem siv los tsim cov khoom siv hluav taws xob thiab cov xov hluav taws kub siab.
Lwm cov Nta: tungsten purity feem ntau ntau tshaj 99.95%; Cov kev ua haujlwm uas pom zoo yuav tsum qis dua 25 {{{} {{{{{} degree; Tus txiv neej dub tungsten tus pas yog 0.2965 ntawm 2027 degree; Thaum 1600 degree, cov coefficient ntawm thermal expansion yog 4.98x {9}}. Qhov tshwj xeeb cua sov muaj peev xwm ntawm 1400 degree yog 0.16J \/ GUCE; Thiab tungsten raj vauv muaj kuab paug yog tsawg.
