Cerium oxide is an inorganic substance with the chemical formula CeO2. It is a yellow or yellow-brown auxiliary powder. The density is 7.13g/cm3, the melting point is 2397 °C, insoluble in water and alkali, slightly soluble in acid. At a pressure of 2000 °C and 15 MPa, cerium trioxide can be obtained by hydrogen reduction. When the temperature is 2000°C and the pressure is 5MPa, the product is light yellow, reddish and pink. Its properties can be used in polishing materials, catalysts, catalyst carriers (additives), ultraviolet absorbers, fuel cell electrolytes, automotive exhaust absorbers, electronic ceramics, etc.
use
Oxidant. Catalysts for organic reactions. Steel analysis is used as a standard sample for rare earth metals. Redox titration analysis. Decolorized glass. Vitrified enamel sunscreen. Heat-resistant alloys.
It can be used as an additive in the glass industry, an abrasive material for flat glass, and an anti-ultraviolet function for cosmetics. It has been extended to the grinding of glass glass, optical lenses and picture tubes, and plays a role in decolorization, clarification, and ultraviolet absorption of glass and wires.
