Ceramic balls are widely used in precision bearings, medical devices, aerospace, automotive, and high-temperature corrosion-resistant equipment. Ceramic balls made from different materials exhibit significant differences in core properties such as hardness, density, temperature resistance, and corrosion resistance. Below is a comparison table of the parameters for four mainstream ceramic ball types to assist with product selection.
| Parameter | Zirconia Ceramic Balls | Alumina Ceramic Balls | Silicon Carbide Ceramic | Silicon Nitride Ceramic Balls |
