Silicon Nitride ceramic :



Is a superhard material, which has lubricity and wear resistance. It does not react with other inorganic acids except for hydrofluoric acid, moreover,

it has strong corrosion resistance and high temperature oxidation resistance.

And it can also resist cold and heat shock, heat up to more than 1000 degrees in the air, rapid cooling and then rapid heating, and will not break.

Features:

A. High Strength over a wide temperature range
B. High Fracture toughness
C. High Hardness
D. Outstanding Wear Resistance ,both impingement and frictional modes
E. Good Thermal Shock Resistance
F. Good Chemical Resistance

Application of si3n4 balls:


Most ceramic balls are mounted in the bearing (high-speed bearing, high precision bearing, vacuum bearing, high/low-temperature bearing, nonmagnetic bearing, high precision ball screws) for the high technology industry, such as aerospace and national defense and etc. The ceramic balls can also be used for chemistry, metallurgy, medical treatment, food industry, oilfield, electronic engineering and etc.
