Particle size: micrometer level, nanometer level (can be customized produced according to customer requirements).
Appearance: Light yellow powder, orange yellow powder.
Characteristics: Pure bismuth trioxide is available in alpha and beta forms. Bismuth trioxide alpha type is a yellow monoclinic crystal system with a relative density of 8.9 and a melting point of 825 ℃. Bismuth trioxide is soluble in acid, insoluble in water and alkali, and soluble in strong acids to form bismuth salts. Bismuth trioxide beta type is bright yellow to orange, with a tetragonal crystal system. Easy to be reduced to metallic bismuth by hydrogen, hydrocarbons, etc. The product has high purity, small particle size, uniform distribution, large specific surface area, high surface activity, low bulk density, high refractive index and dielectric constant, significant fluorescence characteristics and inertness.
