Sintered zirconium silicate (SZS) grinding media, 2.5–2.8 mm. The entry point into ceramic media. Higher density than alumina and stronger than ZTA at ≥1,400 N crushing strength, at a fraction of the cost of stabilized zirconia. The workhorse choice for paint, ink, and coatings production where throughput and cost per kilogram matter more than ultimate purity.

Applications

  • Paints and coatings: pigment dispersion and letdown
  • Printing inks: solvent- and water-based systems
  • Chemical processing: bulk wet grinding and dispersion
  • Ceramics and minerals: cost-sensitive high-volume milling

Compatible Equipment

Ball mills, agitator bead mills, basket mills, and attritors. Suitable for wet and dry milling.

Where SZS Fits

Zirconium silicate sits between alumina and stabilized zirconia. It grinds harder and lasts longer than alumina, and costs far less than zirconia, but its lower density limits energy transfer in high-viscosity systems, and it is not suitable where zirconium, aluminum, or silicon contamination is a specification. For battery materials, electronic ceramics, or pharmaceuticals, use yttria- or ceria-stabilized zirconia.
