Product Description
Zirconium Silicate (CAS 10101-52-7), also known as zirconium(IV) silicate or zirconium orthosilicate, is an inorganic compound with the chemical formula ZrSiO₄. It is valued for its high refractive index, hardness, thermal stability, and resistance to many chemical environments.
In finely ground form, zirconium silicate is widely used in ceramic manufacturing to control opacity, whiteness, and surface appearance. Its performance depends on particle-size distribution, purity, and the formulation in which it is incorporated. Coarser grades may be suitable for refractory and foundry applications, while finer grades are often selected for glaze and ceramic-body formulations.
Available specifications may vary by grade. Before purchasing, confirm the required particle size, chemical composition, whiteness, impurity limits, and intended application against the product's technical data sheet and certificate of analysis.
