• 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

  • Characteristics of Zircon Sand and the Effect on Foundry

    Although silica sand is the most universally available material suitable for foundry mould, other refractory materials are known to be better suited to extreme conditionsIn this respect zircon sand has been found to be the most notable of the materials with high refractoriness, free from sudden volume changes unlike the case of silica which undergoes αβ quartz phase transformation at

  • Zircon an overview | ScienceDirect Topics

    Highgrade zircon sand is largely used in the foundry industry for moulding It does not wet the molten metal, thus giving a better and smoother surface to the casting Zirconia occurs naturally as baddeleyite, or is prepared from zircon Pure zirconia has a low thermal conductivity and high volume change on heating, about 9% contraction at 1000–1100 °C, giving rise to poor thermal shock
