Ceramic balls are precisely fabricated spheres with a high degree of roundness. They are mainly made from several types of ceramic materials. One common type is alumina ceramic, which is composed of aluminum oxide. Alumina ceramic balls are widely used for their relatively high hardness and good wear resistance. Another important material is zirconia ceramic, made from zirconium dioxide. Zirconia ceramic balls offer excellent toughness and chemical stability. Silicon nitride ceramic balls, made of silicon nitride, are known for their high strength and low coefficient of friction, making them suitable for high - performance applications.
The production of ceramic balls typically involves several steps. First, the raw ceramic materials are prepared. Powders of the chosen ceramic materials are carefully weighed and mixed. Then, they are formed into spherical shapes. This can be done through methods like isostatic pressing, where the powder is compressed uniformly in all directions to create a pre - formed ball. After shaping, the pre - formed balls are sintered at high temperatures. Sintering helps to densify the ceramic material, improving its mechanical properties. Finally, the sintered balls undergo precision grinding and polishing processes to achieve the required roundness, surface finish, and dimensional accuracy.
