Utilized in the field of ceramics, zircon plays a crucial role in ceramic tiles, sanitary ware, and tableware due to its opacity, whiteness, wear resistance, and moisture resistance. It is also applied in the refractory industry to safeguard the interiors of high-temperature furnaces. In foundries and precision casting processes, zircon is employed for casting metals and alloys into diverse products, leveraging its thermal stability, high melting point, and abrasion resistance.
Additionally, zircon finds significance in the production of various zirconia chemicals, contributing to ceramics, refractory materials, catalysts, coatings for electronics, and biomedical products. Notably, some zircon serves as an x-ray filter and polishing agent in the manufacturing of silicon wafers for semiconductor components, including integrated circuits (computer chips).
