Ultra high purity 99.99%! Indian niobium pentoxide | Optimal high-performance oxide for optical glass and electronic materials.
Niobium pentoxide (Nb₂O₅) is a white to grayish-white powdered oxide that is an important material widely used in electronic materials and optical fields. This product is of Indian origin and is OPTICAL GRADE (purity of 99.99% or higher), adopting a powdered form (100% below 20 mesh) with extremely high transparency and refractive index control. It is specifically designed to achieve both high transparency and high refractive index in optical glass and optical thin films, and is utilized in cutting-edge optical devices, lenses, and electronic components. Furthermore, the impurity levels are kept below ppm (with Fe, Cr, Cu, Mn, Mo, and Ni all below 2 ppm), and strict quality control compliant with international standards is implemented. We can flexibly respond from sample supply to mass production scale, ensuring stable supply for research and development as well as commercial applications, primarily in the European and Japanese markets. Each lot is analyzed using ICP-OES and XRF, and a COA and SDS are issued. The product is provided in drums with moisture-proof liners, ensuring long-term stability through storage away from direct sunlight and humidity. Additionally, we actively incorporate recycled materials, supporting sustainable sourcing. The adoption of this product is also expanding in next-generation optical devices and advanced electronics fields.
