Bismuth Oxide

Bismuth Oxide – Versatile Metal Oxide for Electronics, Glass & Pigments

We supply high-purity Bismuth Oxide (Bi₂O₃) in various commercial grades. This heavy metal oxide is valued for its high density, brilliant yellow color, and unique electrical properties. Consequently, manufacturers actively use it in electronic ceramics, specialty glass, and as a non-toxic pigment. Moreover, its role as a safer lead substitute in many applications makes it an increasingly important material across multiple high-tech and traditional industries.

Core Applications for Bismuth Oxide in Manufacturing

This versatile oxide serves critical functions in electronics, materials science, and chemical synthesis. Its applications leverage its specific physical and chemical properties.

First, the electronics and ceramics industry relies on bismuth oxide as a key dopant and sintering aid in varistors, capacitors, and ferrites. It enables lower firing temperatures and improves the performance of electronic components. Therefore, manufacturers of multilayer ceramic capacitors (MLCCs) and zinc oxide varistors depend on it for reliable, miniaturized electronics.

Second, the glass and enamel industry utilizes it to produce high-refractive-index optical glass, crystalline glaze finishes, and as a fluxing agent. Furthermore, it serves as an effective non-toxic yellow pigment in plastics, coatings, and cosmetics, replacing lead and cadmium-based alternatives.

Third, the chemical and pharmaceutical sectors employ it as a catalyst in polymerization reactions and as a precursor for other bismuth salts used in gastrointestinal medicines and catalysts.
