1,product details



Ceramic ball (zirconia ZrO2)

Product Name

Ceramic ball (zirconia ZrO2 )






Above 83


2.9-3.1 g/cm3


Zirconia ceramic has a series of good properties,such as high strength,good fracture toughness,high density,good abrasion resistance,high hardness and so on.Zirconia ceramics can be used as good abrasive and efficient grinding media.


They are widely used in aviation, spaceflight, navigation, petroleum, chemical industry, metallurgy, electric power, automobile, textile, machinery, pumps, medical equipment, etc.

Chemical composition

ZrO2:  95%          Y2O3:  5%


Ceramic ball (silicon Si3N4)

Product Name

Ceramic ball (silicon Si3N4)






1,59% lighter than steel ball, which means less centrifugal force and less wear on the groove during high speed and acceleration.

2. 44% larger elastic modulus, which means less deformation under load

3. Harder with Rockwell hardness as 92

4. Smaller friction coefficient

5. Only 1/4 coefficient of thermal expansion of steel, can endure sharp fluctuation of temperature

6. Superior surface finish can be achieved, Ra could be 4~6 nm

7. Can endure high temperature with high hardness and strength up to 1050°C

8. Never rust, and can roll without lubrication.

9. More corrosion resistant than steel.


Si3N4 be first choice for high-demand bearing ball material and valve ball. Si3N4 ball can also be used as valve ball and metering ball in chemical pump, high-temperature pump, metering pump. Si3N4 ball can also be used in linear slider for high temperature and corrosion resistance.
