What is the role of cerium oxide in polishing?

Cerium oxide plays a key role in polishing. Cerium oxide is a white powder with high hardness and abrasive properties. During the polishing process, cerium oxide particles are added to the polishing liquid. Friction with the surface to be polished generates an abrasive effect. Due to the high hardness of cerium oxide particles, they can effectively smooth out the tiny bumps on the surface, making it smoother.

Cerium oxide also undergoes a chemical reaction that can protect the surface from erosion caused by the external environment. This compound exhibits high stability and wear resistance, which aids in preserving the surface quality after polishing.

Deci, cerium oxide is widely used in the polishing of metals, ceramică, sticlă, și alte materiale. It is commonly utilized in automobile repair, watch manufacturing, jewelry processing, and various other industries. For glass polishing, the application of cerium oxide polishing liquid can effectively enhance the smoothness of the glass surface, improving its light transmission, reflectivity, and refractive index. This, in turn, enhances the accuracy and clarity of optical devices.
