Zircon Sand

Finest Mineral


Malli Minerals International is a professionally managed enterprise actively engaged in the supplying of Zircon Sand Minerals to global market.

Zircon sand is a naturally occurring mineral known for its striking reddish-brown to yellowish-brown color and exceptional resistance to heat and abrasion. It is primarily composed of zirconium silicate (ZrSiO4) and is valued for its diverse applications in industries ranging from ceramics and foundries to electronics and nuclear reactors. Zircon sand’s high melting point, chemical inertness, and unique optical properties make it a valuable resource in manufacturing processes, including the production of ceramics, refractories, and high-precision casting.

Typical applications include

  • 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.
  • 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.
  • 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.
  • Nuclear Reactors: Zirconium, derived from zircon sand, is used in nuclear reactors as fuel cladding due to its exceptional resistance to radiation and corrosion.
  • Electronics: Zirconia, a derivative of zircon sand, is employed in electronic components such as oxygen sensors, fuel cells, and solid-state batteries.
  • Abrasives: Zircon sand is used as a high-performance abrasive in grinding wheels, sandpapers, and abrasive belts for applications that demand durability and precision.
  • Chemical Industry: Zircon sand is a source of zirconium compounds used in various chemical processes, including the production of zirconium dioxide and zirconium chemicals.
  • Catalysts: Zirconium compounds are used as catalysts in chemical reactions, particularly in the petrochemical industry.
  • Precision Casting: Zircon sand is used in investment casting processes to create intricate and highly detailed metal components for aerospace, automotive, and jewelry applications.
  • 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.
  • Paints and Coatings: Zirconium compounds are used as opacifiers in paints, coatings, and ceramics to enhance brightness and opacity.
  • Healthcare: Zirconia, a product of zircon sand, is used in dental crowns, implants, and prosthetics due to its biocompatibility and strength.

Product Typical Characteristics

  • Chemical Composition: Zircon sand primarily consists of zirconium silicate (ZrSiO4), with traces of impurities like thorium and uranium.
  • Color: Zircon sand is typically reddish-brown to yellowish-brown, depending on its mineral content and impurities.
  • Hardness: It has a hardness ranging from 6.5 to 7.5 on the Mohs scale, making it a relatively hard material.
  • Density: Zircon sand has a high density, typically ranging from 4.6 to 4.7 grams per cubic centimeter (g/cm³).
  • Melting Point: Zircon sand has a high melting point of approximately 2,550 degrees Celsius (4,622 degrees Fahrenheit).
  • Heat Resistance: Known for its exceptional heat resistance, zircon sand is often used in applications involving high temperatures, such as refractories and foundry molds.
  • Chemical Inertness: It is chemically inert and does not readily react with most chemicals, contributing to its durability and stability.
  • Abrasion Resistance: Zircon sand is highly abrasion-resistant, making it suitable for abrasive applications like grinding and sandblasting.
  • Refractive Index: It has a high refractive index, which is valuable in optical and glass applications for improving clarity and brilliance.
  • Radiation Resistance: Zirconium, derived from zircon sand, exhibits excellent resistance to radiation, making it valuable in nuclear and healthcare applications.
  • Particle Size: Zircon sand products can vary in particle size, with fine to coarse grades available to meet specific industrial requirements.
  • Foundry Characteristics: Zircon sand’s foundry-grade properties include excellent mold strength, thermal stability, and resistance to metal penetration, making it ideal for precision casting.
