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.

Thermal physical and mechanical properties of raw sands ...

Blended sand is made by adding a bond to a ‘washed and dried’ or unboned base sand. This unbonded sand is sometimes called ’sharp sand’, however, the name has nothing about the actual grain shape. The unbonded base sand may be silica, olivine, zircon and others. Each sand has properties that make its use desirable in certain situations [8].
