Foundry Sands and Coatings Zircon Industry Association

Zircon is widely used in the foundry industry, mostly in the form of SAND and FLOUR (milled sand) for casting and refractory applications. Zircon’s properties make it ideal as a moulding base material for sand casting and investment casting, in addition to use as mould coating in die casting and in refractory paints and washes to reduce the wettability of other foundry sands.
