Ultrafine Lanthanum Oxide (La₂O₃), also known as nanoscale lanthanum oxide, is a high-performance rare earth ultrafine powder. It appears as a white, free-flowing powder with strictly controlled ultrafine particle size (typically 10–50 nm), narrow particle size distribution, high specific surface area, and strong surface activity. Different from conventional coarse or flaky lanthanum oxide, our product is produced by advanced ultrafine grinding and classification technology, with strict quality control from raw material selection to finished product inspection. It features high purity (up to 99.999%), excellent dispersion, and stable chemical properties. Widely used in lithium battery cathode materials, automotive exhaust catalysts, high refractive index glass, advanced ceramics, and fuel cell electrolytes, it is a key functional raw material for modern high-tech industry.
