Recently, Sichuan Wonaixi New Materials Technology Co., Ltd. (shortened as “Wonaixi”) has successfully achieved stable mass production of 5N-grade (99.999%) high-purity lanthanum oxide, filling the gap in large-scale domestic production of high-end lanthanide materials and providing critical raw material support for fields such as optics, new energy, and environmental catalysis.
Wonaixi is a national high-tech enterprise and a Sichuan provincial specialized, refined, distinctive, and innovative company. With over ten years of expertise in the research, development, and production of rare earth functional materials, it operates a production line capable of annually manufacturing 15,000 tons of high-purity rare earth salts, leading the industry in core technologies and quality control. The newly mass-produced high-purity lanthanum oxide features total impurities below 10 ppm, with key metallic impurities strictly controlled within 0.1 ppm, offering both high reactivity and excellent dispersibility.
By employing its self-developed precision purification and preparation technology, combined with an intelligent, precise quality control system, the company achieves product purity and particle size stability at internationally advanced levels. This significantly enhances light transmittance in optical glass, ionic conductivity in solid-state batteries, and the service life of environmental catalysts. As a core raw material for lanthanum-based defluorination agents, its high purity strengthens fluoride ion adsorption efficiency, enabling effective treatment of industrial fluoride-containing wastewater.
Currently, Wonaixi’s high-purity lanthanum oxide has entered bulk supply, leveraging its advantages in resources, technology, and production capacity to continuously advance independent and controllable development of high-end rare earth materials in China, empowering the industrial chain’s transition toward higher value-added applications.
