Zircon Flour


Zircon Flour

Details :

  • Zircon flour produced by milling zircon sand to a closely controlled particle size; 99% passing 325 mesh, this zircon flour is especially suitable for the manufacture of frits, refractories and foundry coatings.
  • Zircon Flour is used in the ceramic glaze, glass, refactory and plastic industry.
  • Zircon Flour is ideal for use as an opacifier for glaze frits.
  • Small additions of Zircon Flour improve the mechanical strength of glass and impart alkali resistance to the glass fibres used in glass reinforced concrete.
  • It can be used as a refactory wash for glost klins. It finds use as a fine constituent in pressed zircon refactory shapes and as a filler for epoxy resins.
