NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing comprehensive technical information on the materials we supply. Zirconium Silicate (ZrSiO4), with its CAS number 10101-52-7, is a compound whose unique chemical composition and physical properties underpin its widespread industrial utility.

Chemically, Zirconium Silicate is an orthosilicate of zirconium. Its basic formula, ZrSiO4, indicates a stable compound formed by zirconium cations (Zr4+) and silicate anions (SiO44-). This structure contributes significantly to its inertness and resistance to chemical degradation. The high purity levels, often exceeding 99%, ensure that the material performs optimally in applications where contaminants could be detrimental, such as in high purity zirconium silicate powder used in advanced ceramics.

Physically, Zirconium Silicate typically presents as a white powder, though impurities can sometimes lend it a yellowish or reddish hue. Its high melting point, around 2550°C, is a key attribute, making it an excellent choice for refractory applications. This characteristic is fundamental to its use as zirconium silicate refractory material and in high-temperature processes.

Further physical properties include a high specific gravity (around 4.56 g/cm³) and a Mohs hardness of approximately 7.5, which contributes to its wear resistance. Its insolubility in water and most acids and alkalis is a critical aspect of its chemical stability and broad applicability. These attributes are vital for its function as an opacifier in zirconium silicate for ceramic glaze, ensuring the glaze remains stable during firing.

In foundry applications, the thermal stability of Zirconium Silicate, often referred to as zirconium silicate foundry sand, allows it to withstand the high temperatures of molten metal without breaking down, leading to superior casting quality. Understanding these precise chemical properties and physical characteristics allows industries to leverage Zirconium Silicate effectively for a myriad of industrial applications.
