Zirconium orthosilicate

Zirconium orthosilicate, commonly known as zircon and sold under trade names including Ultrox, Acorite, Zircosil, and Excelopax, is an inorganic salt registered under CAS 10101-52-7 and EC 233-252-7. It carries no assigned E-code and is classified within the Salts and Minerals category.

In coatings and polymer systems, it functions as a crosslinker by forming coordinate bonds with hydroxyl or carboxyl groups, improving film hardness and chemical resistance. In ceramics and refractory applications, its thermal stability enables effective flame retardancy, while in personal care formulations it acts as a surface-conditioning agent on skin and hair substrates.

This material is available in nanopowder grade and supplied in compliance with REACH regulations applicable to European markets. Procurement teams should confirm grade specifications against application requirements, particularly for personal care use where additional regional cosmetic regulations may apply. Standard industrial packaging formats apply; contact your supplier for volume options.
