* The above parameters are for reference only. The specific parameters are subject to actual conditions or customized parameters can be customized according to special requirements.;

It has high strength and toughness, high density, good wear resistance, high temperature resistance and corrosion resistance, high stiffness, non-magnetic conductivity, electrical insulation, and thermal expansion coefficient close to steel at normal temperature.
Advantages: At 600°C, the strength and hardness of zirconia ceramic balls are the same as before.

1. High grinding efficiency: The specific gravity of yttrium-stabilized TZP zirconia ceramic beads is 1.6 times that of ordinary zirconia beads, and has higher grinding efficiency under the same conditions.
2. Good fluidity: The product has good roundness, smooth surface, and lower wear on equipment than other grinding media.
3. Impact resistance and low wear: TZP zirconia ceramic beads have good toughness and will not crack or peel in high-speed, high-concentration machines. The wear is only 1/2 of zirconium silicate beads.
4. Low cost of use: Choosing this product will definitely bring you a reduction in comprehensive costs such as media wear, power consumption, labor, equipment, etc., and greatly improve product quality.
