Ko te Bismuth he ma ki te whakarewa whero ki te whakarewa, te nuinga e whakamahia ana hei whakarite i nga rauemi semiconductor semiconduct, te maero me te kaimoana me nga kaihopu waiu i roto i nga kaiwhakaora karihi. Ko te Bismuth e puta ana i te taiao hei whakarewa koreutu me te kohuke.
Āhuatanga
1.High-Puuite Brisitity e whakamahia ana i roto i te umanga karihi, ahumahi aerospace, ahumahi hiko me etahi atu waahanga.
2.Sinn BISMUTH he mea huna, ka heke te ātete ki te pāmahana pikinga i raro i te pāmahana iti. I roto i te whakatipuranga Thermocoololing me Thermoelectric Armlectric, Bi2te3 me Bi2te3 me te BI2SE3 me nga alloys b-sb-ternary e aro nui ana. I roto i te-bit alloy me te pb-b bi alloy he taonga nui.
3.Kahore he iti o te rewa, he kaha te kaha o te kohurutanga iti, me te waahanga whakawhiti iti neutron iti, ka taea te whakamahi i roto i nga kaihora-pāmahana-pāmahana teitei.
