Cerium hydroxide is light yellow or brownish yellow powder, insoluble in water and weak acid, soluble in concentrated acid, and generates corresponding salt. Absorbing carbon dioxide in the air to produce cerium carbonate. The mixed light rare earth ores were roasted by sodium carbonate and leached by dilute sulfuric acid to obtain the leach solution of rare earth sulfate. Potassium permanganate and borax were added to the leach solution. The solution of tributyl phosphate (TBP)-di(2-ethylhexyl) phosphoric acid (P2O4)-kerosene was used as the extractant to separate cerium and other trivalent rare earth. Cerium hydroxide was prepared by back extraction with sulfuric acid, adding sodium sulfate to the raffinate to form double salt precipitation, filtering, washing, adding sodium hydroxide to transform, filtering and drying.
【Application】
1.It is suitable for ceramics manufacturing.
2.It is resistant to many reactive molten metals such as titanium or uranium.
3.For producing of multilayer ceramic capacitors, Yttrium oxide is also employed as a dopant to reduce the Curie temperature of the barium titanate substrate due to its special properties.
