High Hardness and Durability: Zircon has a high Mohs hardness of 7.5, providing excellent durability and resistance to wear.
Zirconium silicate CAS#10101-52-7
Excellent Chemical Inertness: Its strong chemical stability makes zircon highly resistant to chemical reactions and environmental conditions.
High Melting Point: Zircon can withstand very high temperatures, making it suitable for high-temperature industrial applications.
Improves Casting Surface Quality: Due to its low wettability with molten metals, zircon helps produce smoother surfaces in castings of iron, high-alloy steel, aluminum, and bronze.
Product Details
Zirconium Silicate CAS# 10101-52-7
Zircon (ZrSiO₄) is an accessory nesosilicate mineral commonly found in granitic rocks. Due to its high Mohs hardness of 7.5 and strong chemical inertness, it tends to accumulate in the weathered products of parent igneous rocks, such as alluvial placer deposits and beach sands.
Because of its excellent chemical stability and high melting point, zircon has low wettability with molten metals. This property helps produce smoother and higher-quality casting surfaces in metals such as iron, high-alloy steel, aluminum, and bronze.

Product Application of Zirconium Silicate CAS# 10101-52-7
Zirconium silicate is widely used in the production of refractory materials, particularly in applications that require strong resistance to corrosion from alkaline substances. It is also commonly applied in the manufacturing of ceramics, enamels, and ceramic glazes, where it functions as an effective opacifying agent.
In addition, zirconium silicate may be used as a component in certain cement formulations. It is also utilized in the form of milling and grinding beads for industrial processing. Thin films of zirconium silicate and hafnium silicate can be produced through chemical vapor deposition (CVD) and are considered potential alternative gate dielectric materials to silica in electronic applications.
Furthermore, zirconium silicate is used in cosmetic products in Europe, including creams and powders.
