Bismuth oxide commercial product is yellow powder, insoluble in water, soluble in acid. Is a kind of rare earth metals. Can be carbon and hydrogen reduction. The bismuth nitrate heat decomposition. For making metal bismuth, catalysts and bismuth oxide superconductors.
Also known as bismuth oxide, bismuth oxide is yellow powder, insoluble in water, soluble in acid generated bi (III) salt. The melting point of 824 ° C, the boiling point of 1890 ℃. Is one of the most important compounds of bismuth by hydrogen reduction of metal bismuth. Although bismuth oxide from natural bismuth hua (a kind of mineral), but its main source is usually copper or lead the byproduct of bismuth powder combustion in air can get bismuth oxide.
Is mainly used in chemical industry, such as chemical reagent, bismuth salt manufacturing, etc.) (mainly used for coloring), glass industry, electronic industry, electronic ceramics, etc.), etc. Among them, the electronics industry is the most widely bismuth oxide industry, mainly used in pressure sensitive resistance, thermal resistance, oxide lightning arrester and picture tube, etc. In addition, the Bi2O3 has high refractive index and dielectric constant, significant fluorescence characteristics and idle water. Therefore, Bi2O3 is a kind of very potential of visible light catalyst decomposition and degradation of water pollutants.
