Product Description

Zirconium Silicate Description

Zirconium silicate is a synthetic silicate material with the chemical formula ZrSiO4. It is typically produced from natural zircon sand (whose main component is zirconium silicate) through high-temperature calcination, purification, and refining to obtain a higher purity, more stable, and finer powder product.

It is an extremely excellent ceramic opacifier, whitening agent, and refractory material.  It exhibits exceptional chemical stability at high temperatures and is a key basic raw material in the ceramics, foundry, and refractory industries.

Product Features

Zirconium Silicate Characteristics

1. High Refractive Index: With a refractive index of 1.93-2.04, it is significantly higher than ceramic bodies and ordinary glazes. This gives it strong opacity (opacifying ability) and whitening effect, effectively masking the color of the ceramic body.

2. Excellent Chemical Stability: It remains stable in high-temperature glazes (usually above 1200ºC) and does not easily react with other components in the glaze, preventing glaze defects.

3. High Melting Point and Thermal Stability: It has a high melting point of 2550ºC, a low coefficient of thermal expansion, good thermal shock resistance, and excellent high-temperature performance.

4. High Hardness and Wear Resistance: With a Mohs hardness of 7.5, it provides the product with good wear resistance.

5. Corrosion Resistance: It is resistant to corrosion from various acids, bases, and molten glass and metals.

Product Application

Applications of Zirconium Silicate 

Zirconium Silicate has different kinds of applications in the ceramic industry, including as a whiteness and opacity booster. It's also used as a raw material in ceramic glazes to promote opacity, as well as in glass compounds to make beautiful, opaque white glazes. It improves erosion and chemical resistance when used in glazes.

Zirconium Silicate Powder is a high-quality product with a good refractive index of 1.93-2.01.  it is also widely used in refractory materials, zirconium ramming materials, casting materials spray coatings and dental crowns.
