Pure Ceric Dioxide is a white heavy powder or cubic crystal. The impure products are light yellow or even pink to reddish brown (due to traces of strontium, barium, etc.). Almost insoluble in water and acid. The relative density is 7.3. The temperature of 1950 ° C, the boiling point: 3500 ° C. Toxic. Let me interduce uses of Ceric Dioxide:
1, Oxidizer. A catalyst for organic reactions. Steel analysis is used as a rare earth metal standard. Redox titration analysis. Decolorized glass. Glass enamel sunscreen. Heat resistant alloy.
2, Used as a glass industrial additive, as a plate glass abrasive material, it can also be used in cosmetics to play an anti-ultraviolet effect.
