White Cerium Oxide is an inorganic compound that acts as a catalyst for organic reactions. The pure product is white heavy powder or cubic crystal. The melting point is 2600°C. not soluble in water. Insoluble in sulfuric acid and nitric acid. Cerium oxide is mainly used as an additive in the glass industry, as an abrasive material for plate glass, and can also be used in cosmetics to play an anti-ultraviolet effect. At present, it has been expanded to the grinding of spectacle glass, optical lens, and picture tube, which plays the role of decolorization, clarification, and absorption of ultraviolet rays and electron rays in the glass.
