Rhenium Pellet Description

Rhenium, nrhiav tau nyob rau hauv 1925 los ntawm German kws tshawb fawb Ida thiab Walter Noddack, yog ib qho ntawm cov khoom tshwm sim zaum kawg uas yuav tsum tau txheeb xyuas. Rhenium yog ib qho kev hloov pauv hnyav ntawm cov hlau refractory nrog lub melting point ntawm 3,180 degree thiab muaj lub siab tshaj plaws modulus ntawm elasticity ntawm tag nrho cov refractory hlau (420 GPa). Cov khoom lag luam los ntawm rhenium tuaj yeem raug thermally cycled ntau txhiab zaus tsis muaj teebmeem. Rhenium thiab rhenium muaj cov alloys tshwj xeeb nrog cov ntsiab lus melting siab, siab modulus ntawm elasticity thiab zoo heev kub kub txhua yam khoom. 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).

SSC muaj peev xwm hloov ammonium perrhenate, lossis zoo ib yam ntawm cov khoom siv rhenium-cov kabmob, rau hauv pellets. Rhenium pellets muaj nyob rau hauv cov hlau hauv cov qib purity xws li 99.9 feem pua, 99.95 feem pua ​​​​thiab 99.99 feem pua, thiab tseem tuaj yeem ua kom tau raws li qhov tshwj xeeb. Rhenium pellets yog ib qho tseem ceeb alloying ntxiv nyob rau hauv Ni-base superalloys rau turbines nyob rau hauv dav hlau xyaw. Rhenium pellets kuj tau siv dav hauv tshuaj vapor deposition reactors.
