Zircon
Zircon is a naturally occurring mineral, primarily composed of zirconium silicate (ZrSiO₄). Known for its high density, durability, and resistance to heat and corrosion, zircon is a valuable mineral used across various industries. It is often found in beach sands and riverbeds, where it is extracted along with other heavy minerals.
Applications:
- Ceramics: Zircon is extensively used in the ceramics industry, particularly in the production of glazes and opacifiers. Its ability to impart whiteness and opacity makes it essential for tiles, sanitary ware, and tableware.
- Refractories: Due to its high melting point and thermal stability, zircon is used in the manufacturing of refractory materials. These include bricks, molds, and crucibles that can withstand extreme temperatures, making them ideal for use in furnaces and kilns.
- Foundry Sands: In the foundry industry, zircon sand is utilized as a mold material for casting metals. Its low thermal expansion and high thermal conductivity make it an excellent choice for precision casting, particularly in the automotive and aerospace sectors.
