O le Bismuth o se paʻepaʻe siliva i le uʻamea piniki, lea e masani ona faʻaaogaina e saunia ai mea semiconductor tuʻufaʻatasia, faʻapipiʻi bismuth mama maualuga, mea faʻafefeteina thermoelectric, solders ma faʻafefe vai malulu i reactors faaniukilia, ect. O le Bismuth e tupu i le natura o se uʻamea saoloto ma minerale.
Fa'aaliga
1.High-mama le bismuth e masani ona faʻaaogaina i alamanuia faaniukilia, alamanuia aerospace, alamanuia faaeletonika ma isi vaega.
2. Talu ai o le bismuth o loʻo i ai meatotino semiconducting, o lona teteʻe e faʻaitiitia i le faateleina o le vevela i le maualalo o le vevela. I le thermocooling ma le thermoelectric power generation, Bi2Te3 ma Bi2Se3 alloys ma Bi-Sb-Te ternary alloys e tosina mai ai le tele o le gauai. In-Bi u'amea ma Pb-Bi u'umea superconducting mea.
3.Bismuth e maualalo le faʻafefeteina, maualuga le maualuga, maualalo le mamafa o le vaʻa, ma le vaega faʻafefeteina o le neutron laiti, lea e mafai ona faʻaaogaina i le maualuga o le vevela atomic reactors.
Fa'atatauga
1. E masani ona faʻaaogaina e saunia ai mea faʻapipiʻi semiconductor, mea faʻalili thermoelectric, solders ma faʻafefe vai malulu i reactors faaniukilia.
2. Faʻaaogaina mo le saunia o mea faʻamama maualuga semiconductor ma faʻapipiʻi bismuth mama maualuga. Fa'aaogaina e fai ma fa'amalieina i masini fa'aatomika.
3. E masani ona faʻaaogaina i vailaʻau, mea faʻafefeteina maualalo, fuse, tioata ma ceramics, ma o se faʻamalosi foi mo le gaosiga o le paʻu.
