O le Tantalum o se u'amea iila, lanu siliva e mamafa, mafiafia, malleable ma ductile pe a mama. E maua i ni vaega laiti i minerale (e masani ona faʻatasi ma le niobium), ma faʻaesea e ala i le liua i le oxide ona sosoo ai lea ma le fluoro-complex, K2TaF7, lea e maua mai ai le uʻamea mama e ala ile electrolysis.
O le Tantalum e matua'i fa'a'ele'ele ona o le fa'atupuina o se ata o le oxide, ma e tete'e fo'i i osofa'iga oona (sei vagana ai le HF).
O le a tali atu i alkali fa'afefiloi ma mea eseese e le o ni u'amea i le vevela maualuga.
Tantalum Ingot
Tulaga masani: Q/NSL010-1993, ASTM B 364-92
Mea fa'aletino: lelei le fa'a'ele'ele ma le maualuga o le vevela, malosi lelei, ma'a'a'a a'afiaga, palasitika ma lelei le fa'atinoina o gaioiga ma le vavalalata lelei ma le tino o le tagata.
Fa'aaogāina: o lo'o fa'aaogaina le tantalum e fai ma mea mata'utia mo le tele o mea gaosi tantalum, fa'aaoga lautele i le suau'u, vaila'au, ie, mea tau eletise, gaosiga ma pisinisi gaosi oloa.
Fa'aputuina: pu laupapa pito i fafo o lo'o fa'apipi'iina i mea vaivai.
