ZIRCONIA BALLS: High whiteness and
Features:
1. High hardness.
2. High wear resistance. Alumina ceramic is the material of choice for alumina wear parts.
3. Good tenacity, impact-endurable, no break under high speed impact.
4. Higher density than any other grinding bead brings higher grinding efficiency, thus allowing higher solid proportion or increased material flow.
The main advantages of ZrO2 ceramic ball to steel balls are:
1. It is 23% lighter than the steel ball, which reduces the centrifugal force, rolling and wear of the channel during high-speed and accelerated operation of the bearing;
2. The friction coefficient is small and the rotation flexibility is good;
3, high temperature resistance, the use temperature can reach 750 C, more resistant to chemical corrosion than steel;
4, can work under the conditions of no oil lubrication; no metal pollution; no magnetic; electrical insulation.

Material: ZrO2(94.8%±0.2%) Y2O3(5.2±0.2%)
Characteristics
Good stability, strong acid and alkali resistance.
Has excellent toughness, compressive strength, etc., impact resistance, not broken.
Low abrasion (ppm level), minimal wear on equipment, is the best grinding medium.
The zirconium bead has good roundness, smooth surface, bright, high density, good strength, inertness, and hardness, and is a
perfect and fine spherical grinding medium.
Application areas: Inks, inks, coatings, pigments, fuels, glazes, papermaking, electronic materials, battery materials, silicon
oxide, titanium dioxide, kaolin, calcium carbonate, chemical fiber catalysts, pharmaceuticals, biochemicals, cosmetics and other nanomaterials.
