High purity rhenium hlau hmoov yog lub teeb grey hlau hmoov ua los ntawm agglomerated ib leeg muaju. Peb lav tias peb cov khoom muaj siab tshaj plaws purity, stability, thiab ntawv pov thawj zoo. Rhenium hlau hmoov tuaj yeem siv rau hauv cov khoom ua tiav, xws li cov phaj anode siv hauv kev kho mob. Rhenium hlau yog ib qho nyuaj heev, hnav-tiv taus, corrosion-resistant, thiab muaj tib yam zoo li platinum. Ntshiab rhenium yog mos thiab muaj cov khoom siv zoo. Rhenium muaj qhov melting point ntawm 3180 ℃, qeb thib peb ntawm tag nrho cov ntsiab lus tom qab tungsten thiab carbon. Nws cov ntsiab lus kub yog 5627 ℃, qeb duas ntawm tag nrho cov ntsiab lus. Nws yog soluble hauv dilute nitric acid los yog hydrogen peroxide daws thiab insoluble hauv hydrochloric acid thiab hydrofluoric acid. Rhenium, raws li cov hlau tsis tshua muaj nrog cov ntawv tshwj xeeb, ua lub luag haujlwm tsis tuaj yeem hloov pauv hauv cov hlau kub kub rau cov tshuab aerospace. Rhenium yog siv los tsim cov kev ua haujlwm siab ib leeg siv lead ua kub-kub alloys thiab siv rau cov hniav ntawm lub tshuab aerospace. Nws yog ib qho tseem ceeb ntawm cov khoom siv tshiab tshiab. Rhenium yog qhov ruaj khov ntawm qhov kub thiab txias, nrog rau qhov tsis tshua muaj vapor siab, hnav tsis kam, thiab muaj peev xwm tiv taus arc corrosion, ua rau nws yog ib qho khoom siv zoo heev rau kev tu cov hluav taws xob tsis siv neeg.

Daim ntawv thov:

Siv los ua ib qho ntxiv rau rhenium high-temperature alloys, txheej txheej rau foob pob ua ntxaij cav thiab satellite cav, atomic reactive cov ntaub ntawv, thermal ionization huab hwm coj spectrometer, tshuaj tsuag hmoov
Cov khoom lag luam rhenium xws li rhenium granules, rhenium strips, rhenium daim hlau, rhenium rods, rhenium foils, thiab rhenium xov hlau yog cov ntaub ntawv yooj yim.

Tshuaj Specification:

Re-standard≥99.99% (Xam los ntawm txoj kev rho tawm, tsis suav cov khoom siv roj) Re-ultrapure≥99.999% (Xam los ntawm txoj kev rho tawm, tsis suav cov khoom siv roj) oxygen: ≤600ppm

Particle loj: -200 mesh, D50 20-30um los yog raws li tus neeg thov kev thov muab laser particle loj faib cov ntaub ntawv los yog SEM duab raws li ib tug neeg thov.
