Silica (SI3N4) ceramic ball
Advantages of silicon nitride ceramic ball:
1. High hardness. The vickers hardness of normal Gcr15 bearing steel is 800HV, while zirconia ceramic ball has a hardness of more than 1700HV.
2. High wear resistance. For example, the process of processing products of our company, ordinary steel ball milling (the remainder one millimeter) takes about two to four hours, while the processing of silicon nitride can take at least 150 to 200 hours.
3. Corrosion resistance. The stability of the ceramic material is the best, especially silicon nitride balls, almost does not react with any material, widely used in petroleum, chemical, food and so on need contact with strong strong oxidant and reducing agent industry.
4. High temperature resistance. Ceramic ball in the sintering process go through thousands of degrees of high temperature and pressure, the internal molecular structure is very stable, arrangement is very compact, this makes the thermal expansion coefficient is low, the temperature changes in the structure size almost has no effect. The working temperature of ceramic balls can reach 1200 degrees Celsius or higher, and the low temperature has little influence on them, so it is widely used in space.
5. Light weight. Ceramic balls weigh only 50-60 per cent of the average steel ball and have a promising future in the field of bearings and aerospace.
6. Self-lubricity. The ceramic ball itself has good self-lubricating performance and high machining accuracy. It can reach G5, G10, ceramic ball wear-resistant and stable structure, not easy to deform, so it can be processed and applied to many special industries.
7. Insulation. Ceramic has good insulation effect.
