Ceramic balls are spherical ceramic products made of kaolin, feldspar, alumina powder and other main raw materials. The following is some specific information about ceramic balls:

Main types

Alumina ceramic balls: The main component is alumina, with high strength, high hardness, high wear resistance, high temperature resistance, corrosion resistance, pollution-free and other characteristics. They are commonly used grinding bodies for fine grinding equipment such as ball mills.

Zirconium oxide ceramic balls: At room temperature, they have high strength and high toughness, good wear resistance, high temperature resistance and corrosion resistance, high rigidity, non-magnetic conductivity, and electrical insulation. At 600°C, the strength and hardness are almost unchanged, and the thermal expansion rate is close to that of metal, and can be used in conjunction with metal.

Silicon nitride ceramic balls: Precision ceramics sintered at high temperature in a non-oxidizing atmosphere, with high strength, high wear resistance, high temperature resistance, corrosion resistance, acid and alkali resistance, can be used in seawater for a long time, are insulated from electricity and magnetism, and have almost unchanged strength and hardness at 800°C, low density, small centrifugal force during rotation, can achieve high-speed operation, and are self-lubricating.

Silicon carbide ceramic ball: The product has stable performance, is lighter than steel, has a small friction coefficient, good motion performance, an elastic modulus 50% greater than that of steel, and a thermal expansion coefficient less than 25% of that of steel. It can maintain high strength and hardness at high temperatures before 1000°C, is corrosion-resistant, rust-free, non-magnetic, and can work without oil lubrication.
