The main USES of nano-cerium oxide are: 1. Cerium oxide is used as a glass additive to absorb ultraviolet and infrared rays and has been used in automobile glass.Not only can prevent ultraviolet ray, also can reduce the temperature inside the car, thereby save air conditioning electricity.2. The application of nano-cerium oxide to automobile exhaust purification catalyst can effectively prevent a large amount of automobile exhaust gas from being discharged into the air.3. Nano cerium oxide has been widely used in polishing materials.4, nanometer cerium oxide can also be used in hydrogen storage material, thermoelectric materials, nano oxide cerium tungsten electrode, ceramic capacitors, piezoelectric ceramic, nanometer cerium oxide, silicon carbide abrasive, fuel cell materials, gasoline catalyst, some permanent magnetic material, all kinds of alloy steel and non-ferrous metals, etc.
