I-Bismuth yisilivere emhlophe ukuya kwintsimbi epinki, esetyenziswa kakhulu ekulungiseleleni imathiriyeli ehlanganisiweyo ye-semiconductor, iikhompawundi ze-bismuth ezicoceke kakhulu, imathiriyeli yefriji ye-thermoelectric, ii-solders kunye nezithwala zokupholisa ulwelo kwiireactors zenyukliya, ect.I-Bismuth yenzeka kwindalo njengentsimbi yasimahla kunye neeminerali.
Uphawu
I-1.I-bismuth yococeko oluphezulu isetyenziswa ikakhulu kushishino lwenyukliya, ishishini le-aerospace, ishishini lombane kunye namanye amacandelo.
2.Njengoko i-bismuth ineempawu ze-semiconducting, ukuchasana kwayo kunciphisa ngokunyuka kweqondo lokushisa kumaqondo aphantsi.Kwi-thermocooling kunye ne-thermoelectric power generation, i-Bi2Te3 kunye ne-Bi2Se3 alloys kunye ne-Bi-Sb-Te ternary alloys zitsala ingqalelo enkulu.I-in-Bi alloy kunye ne-Pb-Bi i-alloy zizinto eziphezulu ze-superconducting.
I-3.I-Bismuth inomlinganiselo ophantsi wokunyibilika, ubuninzi obuphezulu, uxinzelelo lomphunga oluphantsi, kunye necandelo elincinci le-neutron lokufunxa, elinokusetyenziswa kwi-reactors ye-athomu ephezulu yobushushu.
Isicelo
1. Isetyenziselwa ikakhulu ukulungiselela imathiriyeli ekhompawundi yesemiconductor, imathiriyeli yefriji ye-thermoelectric, ii-solders kunye nezithwala zokupholisa ulwelo kwiireactors zenyukliya.
I-2.Isetyenziselwa ukulungiselela izinto ezicocekileyo ze-semiconductor kunye ne-high-purity bismuth compounds.Isetyenziswa njengesipholisi kwiireactor zeathom.
3. Isetyenziswa kakhulu kwiyeza, i-low melting point alloy, i-fuse, iglasi kunye neeseramics, kwaye ikwayi-catalyst yemveliso yerabha.
