Silicon nitride ceramic balls possess high strength, hardness, high wear resistance, high temperature resistance, and resistance to acid and alkali corrosion. They also exhibit self-lubricating properties and have a density of approximately 3.20g/cm, which is more than twice as light as steel balls. These ceramic balls can be effectively utilized in a wide range of conditions including environments with temperatures ranging from-150°C to 1400°C, corrosive environments,lack of lubricating medium, and high pollution levels. Silicon nitride ceramic balls are considered the preferred choice for ceramic ball bearings and represent the future development direction of the bearing industry.

The CF-HQ powder manufactured by our company serve as the primary material for producing silicon nitride serves ceramic structural components. CF-HQ utilizes high-purity silicon powder as its raw material. By employing the direct nitridation method in conjunction with our company’s well-established and standardized process control, CF-HQ obtains several advantages including high purity, a significant a phase content, a narrow particle size distribution, and excellent sintering activity.
