The application prospects of nanometer cerium dioxide are promising and related research is continuing to deepen.

Nano-cerium dioxide, also known as nano-cerium oxide, refers to rare earth oxides with a diameter of less than 100 nanometers and a product appearance of milky white or light yellow loose powder. Nano-cerium dioxide is slightly soluble in acid and insoluble in water and alkali. It has the characteristics of low production cost, large specific surface area, good particle dispersion, and good UV shielding. It is widely used in electronic ceramics, polishing materials, UV absorbers, fuel cell electrolytes, Automobile exhaust absorbents and other fields have broad application prospects.

The preparation methods of nanometer cerium dioxide include hydrothermal method, sol-gel method, precipitation method, combustion method, etc. The sol-gel method and the precipitation method have problems such as poor yield of finished products and are not suitable for large-scale production; the hydrothermal method refers to using cerium hydroxide as the main raw material and preparing nano-cerium dioxide through hydrothermal reaction. This method has the characteristics of finished granules It has the advantages of easy path control and good crystallinity, and is suitable for large-scale production. It has now become the mainstream preparation method of nano-cerium dioxide.

According to the “2023-2028 China Nano Cerium Dioxide Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center , Nano-cerium dioxide has a wide range of applications, including electronic ceramics, polishing materials, ultraviolet absorbers, fuel cell electrolytes, automobile exhaust absorbents, etc. In the field of electronic ceramics, nanometer cerium dioxide can effectively improve the smoothness and density of ceramics; in the field of polishing materials, nanometer cerium dioxide can be used for precision processing of optical components; in the field of ultraviolet absorbers, nanometer cerium dioxide can be used to produce sunscreen fibers , sunscreen cosmetics, etc.

In recent years, Chinese enterprises and related scientific research institutions have continued to increase research on nano-cerium dioxide and have made many new progresses. In 2020, Jinan University Professor Chen Duifeng’s team discovered the ceria/ZIF composite nanosystem, which is expected to play an important role in the treatment of ischemic stroke. As research on the production technology and application of nano-cerium dioxide continues to deepen, its application scope will be further expanded.

The main global manufacturers of nano-cerium dioxide include American Elements Corporation, American Nanotechnology Company, American Cerion Company, German PlasmaChem Company, etc. The main manufacturers of nano-cerium dioxide in my country include Nanjing Xianfeng Nano Materials Technology Co., Ltd., Hangzhou Jiupeng New Materials Co., Ltd., Liaoning Kelong Fine Chemical Co., Ltd., etc. At present, the annual production capacity of the nano-cerium dioxide powder products independently developed by Kelong Co., Ltd. has reached 30 tons, ranking the leading position in my country’s market.

Industry analysts said that nanometer cerium dioxide has the advantages of low production cost, large specific surface area, and good particle dispersion. It is widely used in many fields. It is widely used, and with the continuous deepening of technology and application research, its application scope will be further expanded. At this stage, due to factors such as high technical barriers, most of my country’s nano-cerium dioxide production companies are in the small-scale trial stage. In the future, driven by the technological innovation of local companies, my country’s nano-cerium dioxide production capacity will increase.
