Zircon Sand 80-120 Mesh Used for Investment Casting

Product Description

Zircon Sand 80-120 Mesh Used for Investment Casting

Zircon is widely used in the foundry industry mainly for casting and refractory applications. Zircon's properties make it ideal for use in sand casting, investment casting and as a mould coating in die casting processes. It is also used in refractory paints and washes to reduce wettability of other foundry sands.

Features of 65% Zircon sand for foundry:

1	High refractoriness. Melting point up to 2100-2300ºC.
2	Chemical inertness with chemical stability at high temperatures.
3	Neutral PH with low acidity.
4	High cleanness and a good round grain shape.
5	Good grain size and fineness consistency.
6	High ability to bind with binders including both organic and inorganic ones.
7	Very low thermal expansion coefficient.
8	High thermal conductivity is higher than other foundry sands.
9	Low wettability.

The advantage of zircon sand in the foundry:

1	Good chemical stability and low wettability prevent sand from sticking on castings. It can avoid metal penetration into the mold.
2	A low thermal expansion coefficient makes casting precise shape and prevents casting unshaped.
3	Get a better surface finish of metal/steel casting.
4	High Recyclability.
5	Low wettability and high chemical stability will get recycled and easy to clean and get uniform particles.

Typical applications include:

1	Ceramics	Zircon sand is a key ingredient in the production of ceramics, including high-quality tableware, tiles, and sanitaryware, due to its ability to enhance strength, durability, and heat resistance.
2	Foundry Industry	Used as a mold and core material in the foundry industry to produce precision metal castings, particularly in the aerospace and automotive sectors.
3	Refractories	Zircon sand's heat resistance makes it valuable in refractory materials used for lining high-temperature furnaces and kilns in industries like steelmaking and glass manufacturing.
4	Nuclear Reactors	Zirconium, derived from zircon sand, is used in nuclear reactors as fuel cladding due to its exceptional resistance to radiation and corrosion.
5	Electronics	Zirconia, a derivative of zircon sand, is employed in electronic components such as oxygen sensors, fuel cells, and solid-state batteries.
6	Abrasives	Zircon sand is used as a high-performance abrasive in grinding wheels, sandpapers, and abrasive belts for applications that demand durability and precision.
7	Chemical Industry	Zircon sand is a source of zirconium compounds used in various chemical processes, including the production of zirconium dioxide and zirconium chemicals.
8	Catalysts	Zirconium compounds are used as catalysts in chemical reactions, particularly in the petrochemical industry.
9	Precision Casting	Zircon sand is used in investment casting processes to create intricate and highly detailed metal components for aerospace, automotive, and jewelry applications.
10	Glass Manufacturing	Zirconium dioxide, derived from zircon sand, is added to glass formulations to increase refractive index and improve optical clarity in high-quality glass products.
11	Paints and Coatings	Zirconium compounds are used as opacifiers in paints, coatings, and ceramics to enhance brightness and opacity.
12	Healthcare	Zirconia, a product of zircon sand, is used in dental crowns, implants, and prosthetics due to its biocompatibility and strength.
