1.Material Overview
Characteristics:
|
Yellow Power, insoluble in water, but soluble in concentrated acid to get bismuth(III)salt. It can be reduced by Carbon and hydrogen and decomposed from Heated bismuth nitrate. Applied to make metal bismuth, catalyst and bismuth series oxides superconductor. |
Applications:
|
Mainly applied to chemical industry(such as chemical reagent, bismuth salt manufacturing), glass industry(mainly for coloring), electronic industry( electronic ceramic). Among the above, electronic industry is the most widely used industry. Mainly for piezoresistor, thermosensitive resistance, oxides lightning rod and kinescope field etc. |
