High-purity nano niobium oxide

Technical Parameters

Main Features

Nano niobium oxide is prepared by plasma vapor combustion method, featuring high purity, small particle size, uniform distribution, large specific surface area, high surface activity, and low bulk density. The vapor-phase preparation method overcomes the shortcomings of hard agglomeration, poor dispersion, and low purity of particles prepared by wet chemical methods in the market. With high purity and low impurity content, it meets the requirements of electronic-grade powder materials and can be used in fields such as electronics, alloys, optical glass, and coating for lithium battery cathode materials. 

Application Fields

1. Used as raw material for producing metallic niobium, niobium bars, niobium alloys, niobium carbide, conductive ceramic products, iron niobium compounds, optical glass, and lithium niobate crystals.

2. The rapid development of the electronics industry has highlighted the advantages of refractory metals (tantalum and niobium) as construction materials and functional materials. To meet modern quality standards, tantalum and niobium nanopowders should possess advanced physical and technical parameters and improved structures. Tantalum and niobium have unique and complex physical and chemical properties. Although these two metals share some similarities in certain characteristics, tantalum has other unique advantages, such as biocompatibility with human tissues. The electronics industry consumes about half of the global tantalum production annually, mainly in the form of tantalum powder and wire for high-tech applications, such as miniature capacitors used in telecommunications, memory card production, electronic design, medical implants, and automatic dust collectors. The United States uses 60% of its tantalum for capacitor production, making it the largest consumer and importer of tantalum metal. Tekna Plasma Systems (Canada) and QinetiQ (UK) are leading companies in the field of plasma chemistry applications. Their applied scientific activities focus on the production and use of nanoparticles. For example, Tekna Plasma uses high-frequency induction plasma to synthesize nanomaterials (20-100 nanometers). Research in this area is also being conducted at the Plasma Laboratory of the Inorganic Chemistry Institute of Riga Technical University. Neomat Co. applies fine plasma technology to produce a wide range of nanopowders. In Estonia, plasma chemistry production of tantalum and niobium adopts environmentally friendly technology. Before 1991, Silmet JSC conducted pilot and large-scale trials for the production of tantalum and niobium nanopowders using arc plasma chemistry.

3. High-nickel ternary lithium battery cathode materials (NCM) are considered promising lithium iron phosphate battery cathode materials due to their high specific capacity, lower cost, and excellent safety. Their crystal electronic structure, nickel content, preparation methods, and doping and coating modification methods significantly impact the performance of high-nickel NCM materials. High-nickel NCM layered materials also suffer from poor high-temperature performance and low tap density. Doping and surface coating modification are considered effective ways to improve the material's chemical performance and thermal stability. Nano niobium oxide can significantly enhance the battery's rate performance and cycle performance, with better chemical performance at high temperatures compared to undoped materials, and improved conductivity. Therefore, doping with nano niobium oxide is highly beneficial for improving the material's chemical performance. Coating lithium iron phosphate materials with nano niobium oxide can inhibit changes in crystal structure and metal dissolution during discharge, alter the material's surface chemical properties to enhance its chemical performance, prevent or reduce direct contact between the material and the electrolyte, reduce reactions between the electrolyte and the cathode material, thereby improving safety, rate capability, and service life.

4. Doping and coating modification of lithium battery cathode materials with nano niobium oxide improve the structural stability of lithium cobalt oxide batteries under high cutoff potential through the synergistic effect of composite doping, thereby enhancing their usable power density. Coating modification further improves the conductivity and structural stability of lithium cobalt oxide batteries.
