O le pauta u'amea mama maualuga ole rhenium o se pa'u u'amea lanu efuefu e faia mai tioata fa'atasi. Matou te faʻamautinoa o matou oloa e sili ona mama, mautu, ma faʻamaonia lelei. E mafai ona faʻaaogaina le paʻu uʻamea Rhenium i oloa faʻamaeʻaina, e pei o ipu anode e faʻaaogaina i talosaga faafomaʻi. O le u'amea Rhenium e matua'i malō, fa'alavalava, fa'afefete, ma e foliga tutusa ma le platinum. O le rhenium mama e vaivai ma e lelei mea tau masini. O le Rhenium o loʻo i ai se mea faʻafefeteina o le 3180 ℃, faʻavasega lona tolu i elemene uma pe a uma le tungsten ma le carbon. O lona fa'apuna e 5627 ℃, fa'avasega muamua i elemene uma. E mafai ona solu i totonu o vaifofo faʻamaʻi faʻamaʻi faʻamaʻi poʻo vai faʻamaʻi hydrogen ma e le mafai ona faʻafefe i le vailaʻau hydrochloric ma le hydrofluoric acid. O le Rhenium, e pei o se uʻamea e le masani ai ma faʻaoga faʻapitoa, e faia se sao e le mafai ona suitulaga i mea faʻafefe maualuga mo afi vaalele. O lo'o fa'aaogaina le Rhenium e fa'atupuina ai fa'ameamea e tasi tioata maualuga ma fa'aoga i lau o afi va'alele. Ose alagaoa fa'akomepiuta taua fou. O le Rhenium e matua mautu i le maualuga o le vevela, faʻatasi ai ma le maualalo o le mamafa o le ausa, faʻafefeteina, ma le malosi e tetee atu ai i le arc corrosion, ma avea ai ma mea sili ona lelei mo le faʻamamaina otometi o fesoʻotaʻiga eletise.
Talosaga:
Fa'aaogaina e fai ma mea fa'aopoopo mo u'amea vevela maualuga o le rhenium, fa'apipi'i i luga mo afi roketi ma afi satelite, mea fa'atomu fa'atomu, mea fa'ameamea fa'ameamea, va'ava'a fa'ameamea vevela, fa'afefe pa'u.
O oloa o le Rhenium e pei o le rhenium granules, rhenium strips, rhenium plates, rhenium rods, rhenium foils, ma uaea rhenium o mea autu ia.
Fa'amatalaga vaila'au:
Toe fa'afuainumera≥99.99%(Fa'atatau ile auala toese, e le aofia ai elemene kesi) Toe fa'auluina≥99.999%(Fa'atatau ile auala toese, e le aofia ai elemene kesi)okesene: ≤600ppm
Lapopo'a: -200 mata, D50 20-30um po'o e tusa ai ma mana'oga a le tagata fa'atau e tu'uina atu lipoti o su'ega fa'ata'ita'iga a le tagata fa'atau.
