Zirconia ceramic balls need to have a smooth and bright surface. The smoother the medium surface, the less wear. The factor that determines whether there is light on the surface of the zirconia bead is the smoothness of the spherical surface; the smooth spherical mirror has a good effect, and the rough spherical mirror has a poor effect.

The factors affecting the flatness of the spherical surface mainly include the internal structure of the material and the degree of external processing of the spherical surface. External machining of spherical surfaces refers to polishing operations. The spherical surface of the grinding ball just after sintering is matte. After polishing, the spherical surface will show a mirror effect. The structure includes pores, grain size, liquid phase, etc.
Zirconia ceramic balls have good wear and corrosion resistance and are very suitable for wear-resistant structural ceramics. Due to the excellent properties of zirconia ceramic balls, it has a wide range of applications. In terms of high temperature resistance and corrosion resistance, it can be used in steel, chemistry, automobiles, vacuum equipment, motors, etc. In the high-speed machinery industry, it can be used in machine tools, automobiles, aircraft, satellites, electric motors, general industrial machinery, vacuum equipment, etc.

Zirconia ceramic balls have good mechanical properties and are widely used as engineering structural materials. The life stability of zirconia ceramic bearing balls is higher than that of traditional sliding and rolling bearings, with higher wear resistance and corrosion resistance; zirconia ceramic valves can effectively replace traditional metal alloy valves, especially in harsh working environments , effectively reduce wear and improve corrosion resistance, thereby greatly improving the service life. Zirconia ceramic grinding balls are widely used in various grinding machines.
