Zirconium silicate grinding bead has a medium density (4.0 g/cm3), compared with YSZ bead and CSZ bead, but higher productivity than alumina beads. Our zirconium silicate grinding beads are sintered at high temperature and surface conditioning, free of bubbles and pores.


  • Perfect roundness and extremely smooth beads surface
  • High chemical resistance, can be used in wet grinding and dispersing applications
  • Compacted and homogeneous¬†microstructure


Paint and coating industry

  • Thermal paper coatings, carbon paper coatings
  • Pigments and colouring agents for textiles, plastics and food
  • Titanium dioxide, ultra marine, iron oxide, etc.

Electronic industry

  • Iron and chrome based magnetic materials
  • Electronic grade ceramics

Mineral Industry

  • Alminum hydroxide
  • Rare-earth materials
  • Lead, copper and zinc sulphide
