Zirconium silicate (ZrSiO₄)
Zirconium silicate is a ceramic compound consisting of zirconium and oxygen, which is mainly used in the ceramic industry to dull glazes and create glossy, white and matte finishes on ceramic pieces. This material is known for its excellent heat resistance, which makes it an ideal choice for use in high-temperature glazes. Due to its chemical stability, zirconium silicate does not dissolve easily in glazes, allowing it to keep its structure intact during firing and contributing to a longer durability of the final glaze.
This compound acts as an opacifier, which means that it helps to cover the underlying clay body, providing a uniform, opaque layer that hides variations in the base material, such as clay. White glazes used on tableware, tiles and other decorative pieces often incorporate zirconium silicate to achieve a completely white, matte surface, eliminating the visibility of the clay body.
In addition to its ability to dull, zirconium silicate also has the property of increasing resistance to wear and thermal shock, making it ideal for ceramic pieces that will be exposed to demanding conditions of use.Interesting Fact
Zirconium silicate is extremely resistant to corrosion and heat, which makes it valuable not only in craft ceramics, but also in the refractory industry and as an additive in products requiring high chemical resistance.Helpful Tip
If you are looking for a clean, uniform white finish on your glazes, consider using zirconium silicate. However, be sure not to exceed the amount recommended in the formula, as too much can affect the melting and texture of the glaze.
