Cerium Nitrate, is the optimum materials for manufacturing Cerium-doped catalyst, and also applied in making auto gauze covering. Cerium is added to the dominant catalyst for the production of styrene from methylbenzene to improve styrene formation. It is used in FCC catalysts containing zeolites to provide both catalytic reactivity in the reactor and thermal stability in the regenerator. In steel manufacturing, it is used to remove free Oxygen and Sulfur by forming stable oxysulfides and by tying up undesirable trace elements, such as lead and antimony.
