Bismuth yog silvery dawb mus rau liab hlau, uas yog siv los npaj cov khoom siv semiconductor, high-purity bismuth tebchaw, thermoelectric tub yees cov ntaub ntawv, solders thiab kua cooling nqa nyob rau hauv nuclear reactors, ect. Bismuth tshwm sim nyob rau hauv cov xwm li ib tug dawb hlau thiab mineral.
Feature
1.High-purity bismuth yog siv rau hauv kev lag luam nuclear, kev lag luam aerospace, hluav taws xob kev lag luam thiab lwm yam sectors.
2.Vim tias bismuth muaj cov khoom siv semiconducting, nws qhov kev tiv thaiv yuav txo qis nrog kev nce siab ntawm qhov kub thiab txias. Nyob rau hauv thermocooling thiab thermoelectric zog tiam, Bi2Te3 thiab Bi2Se3 alloys thiab Bi-Sb-Te ternary alloys nyiam tshaj plaws. In-Bi alloy thiab Pb-Bi alloy yog cov khoom siv superconducting.
3.Bismuth muaj cov ntsiab lus melting tsawg, siab ceev, tsis tshua muaj vapor siab, thiab me me neutron absorption cross section, uas tuaj yeem siv rau hauv high-temperature atomic reactors.
Daim ntawv thov
1. Nws yog tsuas yog siv los npaj cov khoom siv semiconductor, cov ntaub ntawv thermoelectric tub yees, cov khoom siv thiab cov khoom siv ua kua txias hauv cov tshuab hluav taws xob nuclear.
2.Siv rau kev npaj cov khoom siv semiconductor high-purity thiab high-purity bismuth compounds. Siv raws li ib tug coolant nyob rau hauv atomic reactors.
3. Nws yog tsuas yog siv nyob rau hauv cov tshuaj, tsis tshua muaj melting point alloy, fuse, iav thiab ceramics, thiab kuj yog ib tug catalyst rau roj hmab ntau lawm.
