Iron and Steel - Used with chemical binders for high quality steel castings and for critical iron castings. It is also used in core and mould washes to improve surface finish. Ceramics - Used as opacifier in glazes and frits to enhance resistance of the finished product against water, chemicals and abrasion and as a whitener in porcelain tiles. Refractories - Used for its high thermal stability and non-wetability against molten metals. Products include bricks used to line steel making furnaces and casting channels for refined steel continuous castings. Advantages of Using Zircon Sand:

• Resists metal penetration and reaction with most alloys
• Does not react with iron oxide = prevent sand burn on defects
• Low thermal expansion = expansion defects are eliminated
• Higher refractoriness than Silica
• Low acid demand value = can be used with all chemical binder systems
• Low binder requirement
• Reduced cleaning and machining
• High specific gravity and high thermal conductivity = castings cool faster than silica sand
