Physicochemical Properties Ntawm Tungsten

Tungsten yog cov hlau - grey lossis silvery- cov hlau dawb nrog lub melting point siab txog 3400 degree, ua rau nws cov hlau nrog qhov siab tshaj plaws melting point. Nws qhov kub hnyiab yog 5927 degree, thiab nws qhov vapor siab tseem qis heev txawm tias qhov kub ntawm 2000-2500℃. Nws qhov ceev yog 19.35 g / cm³, piv rau kub. Thaum kub siab, lub zog tensile ntawm 0.002 μm txoj kab uas hla tungsten hlau yog 450 kg / mm². Tungsten muaj qis tshaj coefficient ntawm thermal expansion thiab compressibility ntawm tag nrho cov hlau, thiab nws lub zog tensile ntawm qhov kub thiab txias tshaj li ntawm lwm yam hlau. Tungsten muaj hluav taws xob zoo thiab thermal conductivity, tsis tshua muaj cua sov dissipation coefficient, thiab hluav taws xob conductivity ntawm 18.1 S (Siemens), tsuas yog ib feem peb ntawm tooj liab.

Tungsten raug cais raws li qhov siab - melting- taw tes tsis tshua muaj hlau lossis cov hlau tsis tshua muaj nyob hauv cov khoom siv hlau thiab cov khoom siv hlau. Tungsten thiab nws cov alloys yog cov khoom siv tseem ceeb tshaj plaws hauv kev lag luam niaj hnub no, kev tiv thaiv, thiab kev siv thev naus laus zis siab, dav siv hauv aerospace, nuclear zog, shipbuilding, automotive, hluav taws xob, electronics, thiab tshuaj industries, thiab lwm yam.
