Cerium Oxide

Cerium oxide (CeO₂) is a fine powder used in polishing, catalysts, UV protection, fuel cells, and ceramics, with variable particle size and surface area.

Glass Polishing

Widely used as a high-performance polishing compound for glass, mirrors, optical lenses, and screens due to its excellent abrasive and chemical properties.

Automotive Catalysts

Used in three-way catalytic converters in vehicles to reduce harmful emissions (CO, NOₓ, and hydrocarbons) by storing and releasing oxygen.

Acts as an electrolyte or oxygen ion conductor in solid oxide fuel cells (SOFCs), improving efficiency and durability.
