High purity 99.9%! Indian pentoxide niobium | Ideal for metallurgy, electronic components, ceramics, and catalysts | Optical glass, aerospace, automotive
Niobium pentoxide (Nb₂O₅) is a white to grayish-white powdered oxide widely used in electronic components, ceramics, catalysts, and metallurgy. This product is of Indian origin, STANDARD GRADE (purity over 99.9%), and is available in powder form (100% below 20 mesh), making it easy to handle and ensuring stable quality. In the metallurgy field, it is primarily used for the production of metallic niobium and as an alloy additive. In electronic component applications, it serves as a dielectric and capacitor material, while in ceramics and optical glass, it is utilized for refractive index control and heat resistance improvement. In catalyst applications, it is employed in oxidation and dehydrogenation reactions. Thanks to a consistent manufacturing system within India, we can flexibly accommodate orders from sample sizes (1kg, 5kg) to mass production scales. Additionally, impurities are strictly controlled at the ppm level, and analysis certificates (COA) and safety data sheets (SDS) can be issued for each lot. We have a proven track record of supply in markets centered around Europe, ensuring stable transportation and high reliability of products with traceability. In recent years, it has gained attention in research for next-generation battery materials and optical devices, and it features a sustainable supply system utilizing recycled materials. It is also adopted as a high-reliability material in the aerospace and automotive fields.
