Product Name:Zirconium Oxide Grinding Jars with Lid

Mitr zirconia ball mill  Simple Introduction: 

1 Good restitance and high strength, while testing rare earth material, it can ensure the abraded material is not mixed with other impurities.
2 With high hardness, high strength, high toughness, high wear resistance and chemical resistance, has been range used in ceramics, refractories, mechanical, electronic, optical, optical fiber communication, clock jewelry, aerospace, biology, chemistry, etc. widely applied in various fields.
3 Pure zirconia is a high refractory material, while the melting temperature achieved 2900 °C it improves the high temperature viscosity of the glaze and expanded temperature range of viscosity, has good thermal stability.

Specification of zirconia jars:

Compared with steel ball, ceramic ball has following advantages:

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 78
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.
10. Free of metal contamination.
11. Non-magnetic
12. Electric isolation
13. No adhesive-wear with metal
14. Contact angular is very large with molten and nearly no reaction
