Rhenium / Rhenium Alloys

Txog Pure Rhenium hlau (Rov qab) thiab Rhenium Alloys

Rhenium yog sab hauv 1925 German zaum hu ua W. Noddack, O. Berg thiab Ida Tacke nyob Berlin.

Rhenium yog lub npe hu ua tom qab “Rhenus”, Latin lub npe rau lub Rhine. Nws yog ib lub caij tsawg tsawg (vam meej 4 x 10 4 ppm nyob hauv lub ntiaj teb crust) thiab tsis tshwm sim nyob rau hauv tej los yogee. Nws muaj nyob rau hauv ores uas muaj molybdenum uas nws yuav tau npaj zoo tu qab tso. Cov hlau yog tau los ntawm hydrogen txo cov potassium perrhenate ntsev, tau los ntawm precipitation ntawm lub perrhenate ion (ReO4) – los ntawm ib cov kua tshuaj oxidized.

Rhenium yog ib tug silvery colored hlau uas resists corrosion thiab oxidation tab sis maj mam tarnishes hauv moist cua. Nws yog soluble hauv nitric thiab Sulphur acids. Cov ntaub ntawv rau cov hlau muaj xws li nws siv raws li ib lub caij alloying nrog tungsten, Cov resulting alloy muaj ib tug heev hluav taws xob kuj ua nws suitable rau hluav taws xob filaments. Rhenium muaj ib melting heev melting taw tes (3,180• Quaj) thiab siv los ua kub thermocouples, hluav taws xob hu thiab thermistors. Rhenium yog ib txoj kev hloov hnyav refractory hlau nrog lub siab modulus ntawm elasticity ntawm tag nrho cov refractory hlau (420 GPa). Rhenium thiab rhenium alloys yog nws nrog melting ntsiab lus, Moduli ntawm elasticity thiab excellent kub mechanical zog. Cov rhenium uas muaj alloys yog molybdenum 41% rhuav (Mo41%Re) thiab molybdenum 47.5% rhuav (Mo-47.5%Re).

Saum toj no yog rau cov lus qhia xwb. Eagle Alloys yuav tsis nyiam accuracy ntawm cov txheej txheem los yog cov ntaub ntawv. Tas ib sab drawings tej zaum yuav tau forwarded rau ib tog thib peb rau outsourcing.
