Application and characteristics of cerium oxide heat-resistant silicone rubber

Cerium oxide is an inorganic substance with the chemical formula CeO2, light yellow or yellowish brown powder. Density 7.13g/cm3, melting point 2397℃, insoluble in water and alkali, slightly soluble in acid. At 2000℃ and 15MPa, cerium oxide can be reduced with hydrogen to obtain cerium trioxide. When the temperature is between 2000℃ and the pressure is between 5MPa, cerium oxide is slightly yellow with red, and pink. Its performance is to be used as a polishing material, catalyst, catalyst carrier (auxiliary agent),ultraviolet absorber, fuel cell electrolyte, automobile exhaust absorbent, electronic ceramics, etc.

As China's leading professional cerium oxide processor and supplier, UrbanMines Tech Limited. has fully utilized China's rare earth resource advantages and the company's separation and extraction technology advantages to serve global customers for 16 years. Heat-resistant silicone rubber is the main use and field of cerium oxide for our customers. Our R&D team compiled this article to answer customers' technical questions.
