Rare Earth Oxides

The rare earth oxides series includes lanthanum oxide, cerium oxide, large-particle cerium oxide, etc. Mostly white or light yellow powder, insoluble in water but soluble in acids, hygroscopic and requires sealed storage. With purity ranging from 3.5N to 5N, strict control of rare earth and non-rare earth impurities, and excellent chemical and optical stability. Mainly used for glass decolorization and polishing, ceramics, electronics, rare earth luminescent materials and cerium metal production. Large-particle grades suit high-end precision polishing and advanced ceramics, serving as key basic materials for optoelectronics, glass and catalysis.
