Rhenium (VI) Oxide Description
Ammonium perrhenate (APR) yog ammonium ntsev ntawm perrhenic acid, NH4ReO4. Nws yog daim ntawv tshaj plaws uas rhenium pauv pauv.
Ammonium perrhenate (APR) yog cov hmoov tsis muaj xim uas yaj tag nrho hauv dej, ethanol, thiab me ntsis soluble hauv NH4Cl. Ntawm kwv yees. 365 degree nws decomposes rau hauv rhenium oxide (Re2O7), ammonia (NH3), thiab dej (H2O) vim thermal decomposition.
Ammonium perrhenate (APR) yog siv rau kev tsim khoom ncaj qha ntawm rhenium-raws li catalysts siv nyob rau hauv petrochemical refining thiab ua cov khoom ua ntej rau ntshiab rhenium hlau hmoov los yog pellets.
Tsis tas li ntawd, nws ua haujlwm ua cov khoom siv ua ntej hauv kev tsim cov rhenium hlau hmoov thiab pellets, ib qho tseem ceeb ntxiv hauv superalloys. Nyob rau hauv ib tug homogeneous sib tov nrog rau lwm yam ntawm cov tshwj xeeb alloys, rhenium hlau hmoov yog siv nyob rau hauv semi-tiav thiab tiav cov khoom, xws li anode daim hlau nyob rau hauv daim ntawv thov kev kho mob.
Thov koj xav thov ib nqe lus saum toj no kom tau txais cov ntaub ntawv nqi raws li koj qhov kev qhia tshwj xeeb.
