Physicochemical Properties:
Yellow heavy powder or monoclinic crystal. Odorless. Stable in air. Soluble in hydrochloric acid and nitric acid, insoluble in water. It turns brownish red when heated, and turns yellow when cooled.
Applications and Usages:
Bismuth oxide is mainly used in electronic ceramic powder materials, electrolyte materials, photoelectric materials, high-temperature superconducting materials, and catalysts. Bismuth oxide is an important additive in electronic ceramic powder materials, and its purity is generally required to be above 99.15%. The main application objects include zinc oxide varistors, ceramic capacitors, and ferrite magnetic materials.
