What is Cerium Hydroxide used for?

Cerium Hydroxide Ce(OH)3, also called Cerium Hydrate, is the important raw material for FCC catalyst, auto catalyst, polishing powder, special glass, and water treatment. Cerium hydroxide is used as a protector in corrosion cells and has been found to be efficient on modulating the redox properties of . It is used in FCC catalysts containing zeolites to provide both catalytic reactivity in the reactor and thermal stability in the regenerator. It is also used to produce cerium salts, as an opacifier to impart a yellow color to glasses and enamels. Cerium is added to the dominant catalyst for the production of styrene from methylbenzene to improve styrene formation.
