Zircon Sand Grade A

66% Purity High Grade Quality Wholesale Zircon Sand

Zircon sand (zircon) is highly resistant to high temperatures, with a melting point of 2750 degrees Celsius. It is imperishable to acid corrosion. 80% of global production is directly used in the manufacturing of casting, ceramics, glass, and refractory materials. A small amount is used in ferroalloys, pharmaceuticals, coatings, leather, abrasives, chemical and nuclear industries. A very small amount is used for smelting zirconium metal.

Containing ZrO265 66% is directly used as the casting material of iron metal in the foundries due to its melting resistance (melting point above 2500ºC). Zircon sand has lower thermal expansion, higher thermal conductivity, and stronger chemical stability than other common refractory materials, so high-quality zircon and other adhesives together have good adhesion and are used in the casting industry. Zircon sand is also used as bricks for glass kilns. Zircon sand and zircon powder have other uses when mixed with other refractory materials

Zircon stone is used in the production of refractory materials (called zircon refractories, such as zirconium corundum bricks, zirconium refractory fibers), casting sand (precision casting sand), precision enamel appliances, and glass, metal (sponge zirconium) and zirconium compounds (zirconium dioxide, zirconium chloride, sodium zirconate, potassium fluozirate, zirconium sulfate, etc.).

It can make glass kiln zirconia bricks, zirconia bricks for steel drums, ramming materials and castables; Adding to other materials can improve its properties, such as adding zirconium sand to synthetic cordierite, can broaden the sintering range of cordierite, but does not affect its thermal shock stability;

Zirconium sand is added to high alumina brick to make high alumina brick resistant to spalling, and the thermal shock stability is greatly improved. It can also be used to extract ZrO2. Zircon sand can be used as high-quality raw sand for casting, and zircon sand powder is the main component of casting paint.

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.

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, Zircon Sand Wholesale Supplier
• Reduced cleaning and machining, Ceramic CPU Gold Processor Recovery Scrap for sale
• High specific gravity and high thermal conductivity = castings cool faster than silica sand
