Yttria Stabilized Zirconia Grinding Media Description

Yttria Stabilized Zirconia Grinding Media are precision-engineered ceramic beads made using rare-earth yttrium oxide as a stabilizer through advanced titration rolling and mid-temperature sintering technology. The dense internal structure features ultra-fine tetragonal zirconia crystals under 0.4 μm, giving the media superior corrosion resistance, exceptional wear performance, and high mechanical strength. With perfectly spherical geometry and tightly controlled particle size distribution, these beads deliver stable, contamination-free performance for demanding nano-dispersion and fine grinding processes. Ideal for use in pin-type and turbine-type bead mills, they support ultrafine processing across industries such as digital inks, lithium battery materials, electronic pastes, pharmaceuticals, and high-purity cosmetics.
