Ceramic balls are small, spherical, and often highly engineered balls made from ceramic materials such as alumina, zirconia, or silicon nitride. These balls are used in a variety of applications, such as bearings, valves, and pumps, due to their high strength, hardness, and resistance to wear and corrosion. Ceramic balls are typically used in high-performance environments where traditional steel balls would not be suitable, such as in high-temperature, high-pressure, or corrosive environments. They can also be used in medical implants and dental applications due to their biocompatibility and non-reactive properties. The manufacturing process for ceramic balls involves forming the raw material into a ball shape, firing the ball at high temperatures, and then grinding or polishing the surface to achieve the desired precision and smoothness. Ceramic balls can come in different sizes, shapes, and grades, depending on the specific application requirements.
