Cerium Oxide: The "High-Efficiency Tool" in the Field of Precision Polishing

In the field of precision manufacturing, the polishing process is a crucial link that determines product accuracy and performance. Cerium oxide (CeO₂), with its unique advantages, has become a recognized "high-efficiency tool" in this field.

The core reason why cerium oxide stands out in the polishing field lies in its dual characteristics of combining efficient physical friction and mild chemical action. From a physical perspective, cerium oxide has a Mohs hardness of approximately 6.5, with moderate hardness and uniform particles. It can not only quickly remove tiny defects on the surface of polished materials through friction but also hardly scratch the substrate. From a chemical perspective, it can react with silicon oxides on the surface of polished materials such as glass and sapphire to form easily peelable complexes, significantly improving polishing efficiency and smoothness. Data shows that its polishing efficiency is 3-5 times that of traditional silicon dioxide polishing materials, and it can easily achieve nanoscale mirror effects, which is beyond the reach of other polishing materials.

In practical applications, the "tool-like" property of cerium oxide is fully reflected. In the optical industry, it is the core polishing material for optical glass lenses and laser resonators, which can increase the light transmittance of lenses to more than 99% and ensure the imaging accuracy of optical instruments. In the semiconductor field, cerium oxide can perform precision polishing on silicon wafers and sapphire substrates (used in LEDs and mobile phone cameras), removing nanoscale uneven defects on the surface and laying a solid foundation for the stable operation of chips and LED devices. In addition, in fields such as automotive glass and high-end ceramic tableware, cerium oxide also endows product surfaces with both wear resistance and gloss through its excellent performance.

Nowadays, with the surging demand for precision components in industries such as consumer electronics, new energy, and aerospace, the application of cerium oxide in the polishing field has become increasingly widespread. As an environmentally friendly rare earth material, it also avoids the potential pollution problems caused by traditional polishing agents. It not only meets the needs of efficient production but also conforms to the trend of green manufacturing, continuously consolidating its status as a "high-efficiency tool" in the field of precision polishing.
