Zirconia beads are high-density ceramic media made from stabilized zirconium oxide. They are widely used in bead mills to achieve fine and uniform particle size reduction. Their high hardness and toughness make them ideal for demanding applications where steel or glass beads wear quickly.

YSZ beads (typically >95% ZrO₂) offer higher density, wear resistance, and impact strength, making them suitable for ultra-fine grinding of hard materials. Zirconium silicate beads are more economical and used for medium-fine grinding of softer materials such as pigments or coatings.

Smaller zirconium grinding beads (0.1–0.5 mm) are used for nano-dispersion and fine particle reduction, while larger zirconium grinding beads (1–3 mm) with larger mass, are suitable for coarse grinding or high-viscosity slurries. The optimal size depends on material hardness, target particle size, and mill type.

Zirconia beads are used in industries such as paints & coatings, inks, battery materials, mineral processing, pharmaceuticals, and agrochemicals. They are especially valued where contamination control, fine particle size, and long service life are critical.

Service life varies depending on the material being ground, bead size, mill speed, and slurry viscosity. In optimized processes, zirconia beads last significantly longer than glass or steel beads, reducing downtime and replacement cost. Zirconia beads service life can vary from few months to one year.

High-purity zirconia beads (95%+ ZrO₂) have excellent chemical inertness and minimal contamination. They are neutral to most dispersions and ideal for sensitive materials like electronic pastes or battery cathode powders.

Our beads are produced under controlled raw material sourcing and advanced sintering technology. Each batch undergoes density testing, hardness measurement, sphericity inspection, and wear-resistance evaluation to ensure consistent performance.

Yes. Zirconia beads can be used in both wet and dry milling environments. Their high wear resistance and thermal stability make them effective even under complex working conditions.
