DIPTI METAL INDUSTRIES
Bismuth Trioxide (Bi2O3) & Metal Powder Manufacturer, Bismuth Powder Supplier & Bismuth Powder Exporter
Dipti Metal Industries is a leading Bismuth Powder manufacturer and Bismuth Powder exporter of Bismuth Trioxide (Bi2O3) micron powder and Bismuth Metal Powder. Based in Mumbai, India, we supply high-purity (99.99%) Bismuth compounds widely used in semiconductors, electronic ceramics, photonic devices, varistors, and solid oxide fuel cells (SOFCs).
Our Bismuth Trioxide (also known as Bismite) is a fine yellow powder offering excellent thermal stability and ionic conductivity. It acts as a safe, eco-friendly alternative to heavy metal oxides. We also manufacture Bismuth Subgallate, Bismuth Subnitrate, and Bismuth Sulfide for pharmaceutical and industrial applications.
Bismuth Trioxide (Bi2O3) & Metal Powder Overview
Bismuth Trioxide is a pale yellow to orange-yellow solid, practically insoluble in water but soluble in acid. It is stable under normal temperatures with a melting point of ~820°C. Due to its high refractive index and dielectric properties, it is indispensable in optoelectronics and ceramics.
We also supply Bismuth Metal Powder (typically -200 to -325 mesh), a brittle metal powder used in low-melting alloys, radiation shielding, and as a non-toxic substitute for lead in various applications. Our production ensures low impurity profiles (Cu, Pb, Zn, Fe < 10 ppm) for critical uses.
