1. Rare Earth Polishing Effect
Rare earth polishing powders possess the properties of rapid polishing speed, smoothness, and long lifetime. Compared with traditional polishing powders, red iron powder, iron oxide polishing powders will not pollute the environment and are easy to be separated from the substances stuck on. For example, it only requires one minute to polish a lens using cerium oxide polishing powder, but at least 30 to 60 minutes using iron oxide polishing powder. Therefore, the rare earth polishing powders have the advantage of low consumption, high-speed polishing, and high polishing efficiency. Additionally, they can maximize polishing quality and working conditions.
High-cerium polishing powders ought to be employed in optical lenses and the like, whereas low-cerium polishing powders can be utilized extensively for polishing flat glass, cathode ray tube glass, eyeglass lenses, and other types of glass.
2. Applications in Catalysts
Cerium dioxide (CeO₂) not only possesses extraordinary oxygen storage and release properties but also acts as the most active of rare earth oxide catalysts. Electrodes play crucial roles in fuel cell electrochemical reactions. Not only is it a necessary part of fuel cells, but also a catalyst of electrochemical reactions. Therefore, cerium dioxide can be added as an additive under most conditions to enhance catalyst catalytic activities.
3. Use in Ultraviolet Absorption Products
Nano CeO₂ composites with SiO₂-coated surfaces are used as the main ultraviolet (UV) absorption materials in luxury cosmetics. This process has the benefit of eliminating the drawback of TiO₂ or ZnO, which is pale color and low UV absorption capacity.
Besides their uses in cosmetics, nano CeO₂ can also be added to polymers to form UV-resistance aging fibers, thus obtaining chemical fiber textiles with strong UV shielding and radiation shielding capability. These are superior to the properties of the current TiO₂, ZnO, and SiO₂. Besides that, nano CeO₂ may be added to coating to resist UV radiation and decelerate the rate of polymer aging and degradation.
Our Cerium Oxide powder (CeO2) is carefully handled during storage and transportation to preserve the quality of our product in its original condition.
