Cerium Oxide Powder

Pure ceria is a heavy white powder or cubic crystal in appearance, while impure ceria is light yellow or pink to reddish-brown. Cerium oxide is non-toxic, tasteless, non-irritating, safe, and reliable. It has stable performance and does not react with water and organic matter. It is an ideal new type of sunscreen or anti-ultraviolet agent.

Applications of Cerium Oxide Powder

Cerium oxide can be used as a catalyst for the organic reaction, steel analysis, rare earth metal standard sample, redox titration analysis, decolorizing glass, opaque agent for glass enamel, heat-resistant alloy, and other cases. It can be used as an additive in the glass industry, as an abrasive material for plate glass, and as the anti-ultraviolet effect in cosmetics. At present, the application of cerium oxide has been extended to the grinding of glasses glass, optical lens, and picture tube, which plays the role of decolorization, clarification, ultraviolet radiation of glass, and absorption of electronic wires.
