Descrição

Descrição geral

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 can be prepared by heating bismuth in air or by heating hydroxides, carbonates or nitrates of bismuth.

Aplicação

General applications of bismuth (III) oxide are:production of optical glasses with high indices of refraction, precursor in the production of other bismuth compounds.
Bismuth (III) oxide is suitable for dental materials to render them opaque to X-rays.
It is used for the synthesis of pure BiFeO₃ perovskite nanoparticles, lead free piezoelectric 0.96(Bi_0.5Na_0.5)TiO₃ - 0.04 BaTiO₃.

Características e benefícios

Preparation of new stabilized, oxide ion-conducting, bismuth vanadate phases by a microwave assisted method, from V₂O₅, Bi₂O₃ and other solid oxides, was reported. These ceramics show promise in solid oxide fuel cells, water-vapor electrolyzers and oxygen sensors.
