Uses & manufacturing
Uses
Used to make cerium salts, colored glass, and opacified glazes/enamels; Crude form used in arc lamps; [Hawley]
Glass Manufacturing [Category: Industry]
Enameling [Category: Hobbies]
General Manufacturing InformationCerium hydroxide (Ce(OH)3): ACTIVE
Applications
UsesThe pure compound is used in glazes and enamels as an opacifying agent. It also is used to make colored glass, imparting yellow color to the glass. The crude form is used in flaming arc lamps. Another application of this compound is in the preparation of several other cerium salts.
Preparation methods
PreparationCerium(III) hydroxide is obtained in industrial scale from monazide sand, (Ce, La, Th)PO4. In the laboratory, it may be prepared by treating caustic soda solution with cerium(III) chloride, followed by crystallization. CeCl3 + 3NaOH → Ce(OH)3 + NaCl.
