The worldwide demand for Zircon is being driven by urbanisation of developing economies, world economic growth and the increasing end applications of zircon. However, the global supply of Zircon is declining due to a depletion in current mines and declining grades.
Almost half of the zircon produced is used in ceramic applications due to its ability to scatter and reflect light. The surface layer of most tiles, bathware and crockery obtain their glazed finish, durability and resistance to discolouration, from zircon included into their surfaces. Zircon usually occurs in lower quantities than titanium dioxide mineral sands deposits and attracts a premium.
Opacifier in ceramics
Floor and wall tiles, sanitary ware and tableware
• Opacity (whiteness)
• High refractive index (Zircon refracts and reflects white light well)
Refractory and foundry steel
Glass production, casting of jet turbine engines
Important constituent of welding to shape, hold and protect the weld pool from atmospheric conditions
