As an electronic functional powder doped material, nano Alpha Bi2O3 Bismuth(III) oxide is widely used in the production of sensitive components, dielectric ceramics electronic components.
In general, monoclinic structure alpha Bi2O3 is the most stable, and its crystal structure contains a large amount of oxygen vacancy, and oxygen ionic has good conductivity and can be used to make all kinds of solid oxide fuel cells and oxygen sensor etc.
Bismuth oxide is often chosen active substances in chemical power, such as excellent mercury-free zinc batteries corrosion inhibitor, electrode material of lithium battery and additives of improving alkaline zinc/MnO2 battery rechargeable performance.
It is found that the rechargeable performance of nanoscale bismuth oxide is better than that of conventional bismuth oxide powder, and as the additive of positive electrode active material EMD of primary battery, it shows excellent performance under deep discharge.
