Product Description
Zirconium Silicate Powder, also known as Zircon Powder, is a high-purity industrial material renowned for its excellent thermal stability and consistent properties. It is widely used in ceramics, refractories, glass, and casting industries. Its high purity ensures quality in high-end ceramic products, while its thermal stability makes it ideal for refractory bricks and high-temperature applications. Zirconium Silicate Powder also enhances the transparency and strength of glass and improves the surface quality of castings.
Zirconium silicate is a high-performance inorganic non-metallic compound synthesized from high-purity zircon sand through a series of precisely controlled processes, including raw material selection, high-temperature calcination, and ultrafine grinding. With the chemical formula ZrSiO4, it exhibits a high melting point, exceptional whiteness, outstanding chemical stability, and pronounced opacifying properties, making it highly effective in applications requiring opacity and durability.

Advantages of Zirconium Silicate:
1. Exceptional opalescence: Delivers superior whiteness and coverage in ceramic glazes, offering far greater cost-effectiveness than alternatives like titanium oxide.
2. Outstanding chemical stability: Resists acids, alkalis, and corrosion, effectively withstanding erosion from molten glass and metal liquids to ensure long-lasting product performance.
3. High Refractoriness: With a melting point of 2550°C, it serves as a key raw material for advanced refractory products, significantly extending kiln lifespan.
4. Excellent Thermal Stability: Low thermal expansion coefficient ensures outstanding thermal shock resistance under rapid cooling/heating cycles, minimizing cracking.
5. High Hardness and Wear Resistance: High Mohs hardness significantly enhances surface durability in products like ceramic floor tiles.
Primary applications of zirconium silicate:
1. Ceramic Industry: Glaze opacifiers, an indispensable component in producing sanitary ware and high-end wall/floor tile glazes.
2. Refractory Materials: High melting point, used for filling and repairing high-temperature kilns.
3. Precision Casting: Employed in investment casting to achieve precision castings with exceptionally smooth surfaces.
4. Other Applications: Coatings fillers, electronic components, chemical raw materials, etc.
