Ideal for industrial use! High-purity niobium pentoxide from Brazil (99.7%) with stable supply available | Electronic components, catalysts, ceramics, metallurgy, optical glass
Niobium pentoxide (Nb₂O₅) is a white to grayish-white powdered oxide widely used in electronic components, catalysts, ceramics, and metallurgy. This product is a STANDARD GRADE from Brazil (purity of 99.7% or higher, calcined basis) and is available in a powdered form (100% < 8 mesh), making it easy to handle and ensuring stable quality. It is utilized across a wide range of industrial fields, including the production of metallic niobium for metallurgical applications, alloy additives, dielectrics and oxide film formation for electronic components, refractive index control in ceramics and optical glass, and oxidation reactions in the catalyst field. We have established a stable import procurement system and can flexibly accommodate orders from sample sizes (1kg, 5kg) to mass production scales (tens of MT/year). This product can be supplied in bulk bags (up to 1,050kg/bag), with each package clearly labeled with the product name and lot number, ensuring traceable management. Analysis certificates (COA) and safety data sheets (SDS) are also available. We manage impurities based on international standards, ensuring stable quality for long-term supply. Additionally, it is widely adopted in the field of electronic materials, including aerospace superalloys and high-temperature ceramics.
