Physical and Chemical Properties | White or slightly with light yellow crystalline powder, the color changes slightly with the change of purity, is orthorhombic crystal system, difficult to dissolve in water. When the aqueous suspension is boiled, the basic carbonate is produced by hydrolysis. In the alkali metal carbonate solution to form insoluble carbonate double salt Ce2(CO3)3? Na2CO3? 2H2O. Can react with most acids to form the corresponding salt. It is decomposed to CeO2 when heated at 900 °c. |
Use | For the preparation of cerium chloride and incandescent lamp cover |

white or slightly light yellow crystalline powder, the color changes slightly with the change of purity, and the rhombic crystal system is difficult to dissolve in water. When the aqueous suspension was boiled, it was hydrolyzed to form the poorly soluble carbonate salt Ce2 (C03)3. Na2c3/2h20. Can react with most acids to form the corresponding salt. It is decomposed to CeO2 when heated at 900 °c.
solvent extraction method: crude Cerium hydroxide was used as raw material, and tributyl phosphate-liquid paraffin and Di (2-ethylhexyl) phosphoric acid-kerosene were used as extraction agent for purification, to obtain cerium chloride hydrochloric acid solution. Then neutralized with ammonia, ammonium bicarbonate is added to precipitate cerium carbonate, and the precipitate is a cerium carbonate product after filtration, washing, centrifugation and drying.
It is mainly used for the preparation of rare earth luminescent materials, automobile exhaust purification catalysts, polishing materials and color engineering plastics. It can also be used for chemical reagents.
The product is sealed and packed in a double plastic bag, and then packed in a woven bag. Store in a dry place, not in the open air. Protection against rain and moisture during transport. See cerium oxide products for toxicity and protection.
