Rhenium hmoov Description
Nyob rau hauv lub ntiaj teb crust, rhenium tshwm sim txawm tsawg dua kub. Nyob rau hauv nws lub xeev ntshiab, rhenium yog ib qho nyuaj heev, ci ntsa iab hlau, zoo ib yam li platinum, thiab tsuas yog tsim los ntawm liab kub. Rhenium yog ib qho kev hloov pauv hnyav hlau refractory. Nws melting point, 3,180 degree, yog qhov siab tshaj plaws ntawm tag nrho cov hlau. Nws muaj qhov kub ntawm 5,596 degree thiab qhov ntom ntawm 21.02 g / cm3. Nws muaj lub siab tshaj plaws modulus ntawm elasticity ntawm tag nrho cov refractory hlau (420 GPa). Vim yog cov khoom tshwj xeeb no, rhenium yog qhov tseem ceeb hauv ntau qhov kev lag luam tseem ceeb xws li aviation.
Rhenium muaj cov alloys tshwj xeeb nrog cov ntsiab lus melting siab, siab modulus ntawm elasticity thiab zoo heev kub kub mechanical zog. Feem ntau cov rhenium uas muaj alloys yog molybdenum 41 feem pua rhenium (Mo41 feem pua Re) thiab molybdenum 47.5 feem pua rhenium (Mo-47.5 feem pua Re).
Rhenium hmoov muaj nyob nrog kev xaiv ntawm qib purity, 99.99 feem pua thiab 99.9 feem pua ntshiab. Mesh loj muaj xws li -200, -325 thiab -635 mesh. Qhov ntau thiab tsawg yog muaj raws li qhov kev thov.
Rhenium tuaj yeem siv los ua alloy additives. Tungsten-rhenium alloy nyob rau hauv pas nrig, phaj, raj, ntawv, thiab hlau cov ntaub ntawv yuav siv tau raws li high-temperature structural ntaub ntawv nyob rau hauv aerospace technology, electron tube, daim duab tube, noob kub hlau, hluav taws xob tiv tauj cov ntaub ntawv, high-temperature thermocouple cov ntaub ntawv, thiab lwm yam Molybdenum-rhenium alloy tuaj yeem siv los ua cov khoom siv rau fusion reactors. Rhenium yog ib qho tseem ceeb heev catalyst. Nws muaj kev xaiv zoo thiab tuaj yeem tuav nws lub peev xwm catalytic txawm tias tom qab kis los ntawm lwm yam tshuaj. Nws yog dav siv hauv kev lag luam petrochemical.
