Buy High purity zircon sand at low price Wedge India with zirconium dioxide (ZrO2) content of 66%, for various industrial applications, excellent thermal stability, chemical inertness, and high melting point.

 

Zircon sand is a naturally occurring mineral predominantly composed of zirconium silicate (ZrSiO4). It is a valuable mineral found in sedimentary, igneous, and metamorphic rocks, and is commonly extracted from coastal and alluvial deposits. High purity zircon sand, typically characterized by a zirconium dioxide (ZrO2) content of around 66%, is used in various industrial applications due to its excellent thermal stability, chemical inertness, and high melting point.

 

Here are some key features and benefits of zircon sand:

Technical Properties
Chemical Composition: Zircon sand primarily consists of zirconium silicate. It may also contain trace amounts of titanium, iron, and aluminum.
Physical Properties: It is typically brownish-red, has a high melting point (about 2,550°C), and is chemically inert.
Density: Zircon has a high density, usually around 4.6–4.7 g/cm³.

 

Applications of Zircon sand
Ceramics: Zircon sand is widely used in the ceramics industry. It is an essential component in the production of ceramic tiles and sanitary ware due to its high refractoriness and chemical stability.
Refractories: Due to its high melting point, zircon sand is used in refractory materials, which are crucial in high-temperature environments such as furnaces and kilns.
Casting and Foundry: In the foundry industry, zircon sand is used for mold and core production, particularly in the casting of metals like aluminum and steel. Its high thermal conductivity and low thermal expansion make it ideal for these applications.
Abrasives: Zircon sand can be processed into fine powders and used as abrasives for polishing and grinding applications.
Chemical Industry: Zircon is a source of zirconium dioxide (zirconia), which is used in various chemical applications, including catalysts, pigments, and electronics.
Nuclear Industry: Zirconium, derived from zircon, is used in the nuclear industry for fuel rod cladding due to its low neutron absorption properties.
Extraction and Processing
Mining: Zircon sand is typically mined from beach sands, alluvial deposits, and river beds using dredging or dry mining techniques.
Separation: The extracted sand undergoes a series of physical and chemical processes to separate zircon from other minerals. This often involves gravity separation, magnetic separation, and sometimes flotation.
Purification: The final product is purified to remove impurities and may be further processed to produce zirconia (ZrO2) or other zirconium compounds.
Environmental and Health Considerations
Radiation: Zircon sand can contain trace amounts of naturally occurring radioactive elements like uranium and thorium, which may pose health risks during handling and processing. Proper safety measures and regulations are necessary to mitigate these risks.
Environmental Impact: Mining and processing zircon sand can have environmental impacts, including habitat destruction and water pollution. Sustainable practices and rehabilitation efforts are essential to minimize these impacts.

Zircon sand is a versatile mineral with numerous industrial applications, particularly valued for its high-temperature stability, chemical inertness, and unique physical properties. Whether used in ceramics, refractories, or the nuclear industry, it plays a critical role in various high-tech and everyday products.
