Several Major Applications of Nano Cerium Oxide

Nano cerium oxide is a relatively cheap and widely used rare earth oxide. Nano cerium oxide has a small particle size, uniform particle size distribution, and high purity. Insoluble in water and alkali, slightly soluble in acid. It can be used as polishing materials, catalysts, catalyst carriers (auxiliaries), automobile exhaust absorbers, ultraviolet absorbers, fuel cell electrolytes, electronic ceramics, etc. Nanoscale cerium oxide can directly affect the performance of materials. For example, adding ultrafine nanometer cerium oxide to ceramics can reduce the sintering temperature of ceramics, inhibit lattice growth, and improve the density of ceramics. A large specific surface area can better improve the catalytic activity of the catalyst. Its price-changing characteristics make it have good photoelectric properties and can be doped into other semiconductor materials for modification, improving the efficiency of light quantum migration and improving the photoexcitation of the material.

Polishing material:

Nanocerium oxide is widely used as a polishing material, especially in the fields of glass, optical lenses, photovoltaic panels, and other fields. Its high hardness and excellent polishing properties make it an ideal polishing material.

Catalysts and catalyst support:

Nanocerium oxide is often used as a catalyst or catalyst carrier to play a catalytic role in chemical reactions. Its high specific surface area allows it to provide more active sites and enhance catalytic activity. At the same time, nanometer cerium oxide is also used in automobile exhaust purification, which can help purify harmful gases.

UV absorber:

Due to its strong UV absorption properties, nanocerium oxide is widely used in products such as sunscreen cosmetics, automotive glass, sunscreen fibers, coatings, and plastics. It can effectively reduce the damage of ultraviolet rays to the human body.

Fuel cell electrolyte:

In fuel cells, nanometer cerium oxide is used as an electrolyte material, which can provide sufficiently high oxygen ion conductivity at lower temperatures to improve fuel cell performance.

Electronic ceramics:

Nanocerium oxide is widely used in the field of electronic ceramics and is used to manufacture electronic components such as capacitors and varistors. Its excellent electrical properties make it an important material.

iron industry:

As a trace additive, nanometer cerium oxide can eliminate impurities, refine grains, improve material structure and properties, improve the mechanical, physical, and processing properties of steel alloys, and increase the thermal stability and corrosion resistance of alloys.

Luminescent and magnetic materials:

Nanocerium oxide also has important applications in luminescent materials and magnetic materials. It can improve the properties of these materials and expand the application fields of these materials.

Overall, nano cerium oxide plays an important role in multiple fields with its versatility and superior performance, providing technical support and solutions for various applications.
