Bismuth Trioxide Micron Powder
Bismuth (III) oxide is a yellow, monoclinic crystalline powder. It is insoluble in water and hydroxide solutions but dissolves in acids to form bismuth (III) salts. It’s density is nearly 8.90 g/cm3; melts at 817°C; vaporizes at 1,890°C and it is insoluble in water; soluble in acids. Bismuth trioxide occurs in nature as mineral bismite. It can be prepared by heating bismuth in air or by heating hydroxides, carbonates or nitrates of bismuth. Thanks to their flexibility, perovskite-oxide materials and derivatives offer a wide range of possibilities to search and optimize novel thermoelectric materials. The advantages of the perovskites are their profound flexibility and relatively simple and therefore predictable structure-property relations. Micron-bismuth oxide powder due to its crystal structure contains a large number of oxygen vacancies, oxygen ion conductivity, can be used to make a solid oxide fuel cell electrolyte, the oxygen sensor, and high purity oxygen generator. Besides, bismuth trioxide micron powders are also used in high-temperature superconducting materials, optoelectronic materials, electronic ceramic powder materials, catalysts, also have a wide range of applications.
