APPLICATONS

ZR - 300 is used in the ceramic glaze, glass, refactory and plastic industry.
ZR - 300 is ideal for use as an opacifier for glaze frits

Small additions of ZR - 300 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.
