Application: | Cerium Sulfate is applied as industrial antioxidant, waterproof materials, and etching agent for the integrated circuit, is also the important raw material for polishing powder, special glass and ceramics. |
Anhydrous cerium sulfate is a yellow crystalline powder. Heat dehydration, 180~200ºC to become anhydrous salt. Decomposes above 350°C to produce cerium oxysulfate. It is soluble in cold water and hot acid, and decomposes into basic salt in hot water. |
