Is Cerium Oxide Dangerous?

Cerium oxide CeO2 powder overview

Cerium oxide is an inorganic substance with a chemical formula of CeO2, a light yellow or yellowish brown auxiliary powder. Density 7.13g/cm3, melting point 2397℃, insoluble in water and alkali, slightly soluble in acid. At a temperature of 2000 °C and a pressure of 15MPa, cerium oxide can be obtained by reducing cerium oxide with hydrogen. When the temperature is free at 2000 °C and the pressure is free at 5MPa, the cerium oxide is yellowish, slightly reddish, and pink. Its performance It is used as polishing material, catalyst, catalyst carrier (auxiliary), ultraviolet absorber, fuel cell electrolyte, automobile exhaust gas absorber, electronic ceramics, etc.

The pure product is white heavy powder or cubic crystal, and the impure product is light yellow or even pink to reddish brown (because it contains trace amounts of lanthanum, praseodymium, etc.). Almost insoluble in water and acid. Relative density 7.3. Melting point 1950℃, boiling point: 3500℃. Toxic, the median lethal dose (rat, oral) is about 1g/kg.

The salt of cerium oxide rare earth element can reduce the content of prothrombin, make it inactive, inhibit the generation of thromboplastin, precipitate fibrinogen, and catalyze the decomposition of phosphate compounds. The toxicity of rare earth elements weakens with the increase of atomic weight.

Inhalation of dust containing cerium can cause occupational pneumoconiosis, and its chlorides can damage the skin and can stimulate the mucous membranes of the eyes.

Maximum allowable concentration: 5 mg/m3 of cerium oxide, 5 mg/m3 of cerium hydroxide, wear a gas mask when working, special protection should be carried out if there is radioactivity, and dust should be prevented from scattering.

Application of Cerium Oxide CeO2 Powder

oxidizing agent. Catalysts for organic reactions. Iron and steel analysis as a rare earth metal standard. Redox titration analysis. Decolorized glass. Glass enamel sunscreen. Heat resistant alloy.

Cerium Oxide CeO2 Powder can be used as an additive in the glass industry, as a grinding material for plate glass, and can also be used in cosmetics to play an anti-ultraviolet role. It has been expanded to the grinding of spectacle glass, optical lenses, and picture tubes, and plays the role of decolorization, clarification, and absorption of ultraviolet rays and electron rays of glass.
