Recently, Sichuan Wonaixi New Material Technology Co., Ltd. (referred to as "Wonaixi") has successfully achieved stable mass production of 5N grade (99.999%) high-purity lanthanum oxide, filling the gap in large-scale production of high-end lanthanide materials in China and providing key raw material support for fields such as optics, new energy, and environmental catalysis.

Wonaixi is a national high-tech enterprise and a specialized and innovative enterprise in Sichuan Province. It has been deeply engaged in the research and development of rare earth functional materials for more than ten years and has an annual production line of 15000 tons of high-purity Rare Earth Salts. Its core technology and quality control are industry-leading. The high-purity lanthanum oxide produced this time has a total impurity content of less than 10ppm, with key metal impurities strictly controlled within 0.1ppm, combining high activity and excellent dispersibility.

The company adopts a self-developed precision purification preparation process, combined with an intelligent and precise quality control system. The product purity and particle size stability have reached the international advanced level, which can significantly improve the optical glass transmittance, solid-state battery ion conductivity, and environmentally friendly catalyst life. As the core raw material of lanthanide based defluorination agents, its high purity characteristics can enhance the adsorption efficiency of fluoride ions and assist in the efficient treatment of industrial fluorine-containing wastewater.

At present, Wonai Rare Earth High Purity Lanthanum Oxide has successfully achieved mass supply. With its advantages in resources, technology, and production capacity, it continues to promote the independent and controllable development of high-end rare earth materials in China, empowering the industrial chain to upgrade towards high added value.
