Black Silicon Nitride Ceramic Bearings Widely Used In Bicycles, Roller Skates, Model Airplanes
Product Description:
One of the key features of Silicon Nitride Ceramics is its excellent dielectric strength. With a dielectric strength of 18-20 KV/mm, this material is highly resistant to electrical breakdown, making it an excellent choice for applications that require electrical insulation. This feature also makes it suitable for use in high voltage environments.
In addition to its mechanical and electrical properties, Silicon Nitride Ceramics also has a low Poisson's Ratio of 0.27. This means that it is highly resistant to deformation under stress, making it an excellent choice for applications that require high dimensional stability.
The density of Silicon Nitride Ceramics is 3.2 G/cm3, making it a lightweight material that is easy to handle and transport. This feature also makes it an excellent choice for applications that require high strength and durability, without adding unnecessary weight.
SI3N4 ceramic ball is one of the most common applications for Silicon Nitride Ceramics. Due to its high strength and durability, SI3N4 ceramic ball is widely used in precision bearings, valves, pumps, and other high-performance machinery and equipment. Its exceptional mechanical and electrical properties make it an ideal choice for applications that require high performance and reliability.
