Application

Usage

Cerium oxide is a widely used rare earth functional material, with its core applications focusing on three major fields: first, the catalytic field, serving as a key oxygen storage material in automotive exhaust three-way catalysts, efficiently purifying pollutants such as CO, HC, and NOx, and also used in industrial VOCs treatment, fuel cell and water electrolysis catalysis; second, precision polishing, acting as a special polishing powder for optical glass, semiconductor silicon wafers, sapphire substrates, and photovoltaic glass, achieving high-precision mirror polishing while balancing speed and surface quality; third, functional materials, applied in ceramic modification, ultraviolet shielding coatings, oxygen sensors, and special optical glass, and also serving as metallurgical additives, environmental remediation materials, and biomedical carriers, covering multiple industries such as high-end manufacturing, environmental protection, new energy, and electronics.
