High purity 99.9%! Indian tantalum pentoxide | Ideal for metallurgy, electronic components, ceramics, and catalysts | Optical glass, aerospace, automotive
Tantalum pentoxide (Ta₂O₅) is a white powder oxide with high dielectric constant, heat resistance, and corrosion resistance, playing an important role as a high-performance material in the industrial sector. This product is of STANDARD GRADE (purity over 99.9%) sourced from India, adopting a powdered form that ensures stable quality and ease of handling. Primarily, it is used in the metallurgy field as a reinforcing material for metallic tantalum and superalloys, while in the electronics sector, it is utilized in capacitors and high-dielectric oxide film materials. Additionally, by adding it to ceramics and optical glass, it contributes to improved heat resistance and mechanical strength, and in catalytic applications, it enhances the efficiency of oxidation reactions in petrochemical and fine chemical processes. Thanks to a consistent manufacturing system within India, we can flexibly accommodate orders from sample sizes (1kg, 5kg) to mass production scales, with a wealth of supply records in the European, American, and Japanese markets. Furthermore, each lot is analyzed using ICP-OES and XRF, and a Certificate of Analysis (COA) is issued, ensuring traceability with product names and numbers. The product is packaged with moisture-proof liners, allowing for long-term stabilization of quality through indoor storage away from direct sunlight and high humidity. It is also gaining attention as a high-reliability component for the aerospace and automotive industries and is widely adopted for research and development purposes.
