Cerium Oxide

Cerium oxide (CeO₂) is a rare earth oxide, typically appearing as a light yellow or white powder. Driven by its dual core functions of "catalysis + polishing," it plays an irreplaceable role as a strategic rare earth functional material in the automotive, electronics, and environmental protection industries. It is widely used in purification catalysis, polishing materials, functional modification, chemical additives, as well as energy and environmental materials.
