Description
At PILATO, we market GLAZE 325 wollastonite for the ceramic industry, particularly for glaze applications. Our company-wide quality management system, together with a service-oriented operations team, ensures immediate product availability and an agile response to customer requirements. We coordinate operations and logistics from end to end to integrate seamlessly into our customers’ supply chains.

The GLAZE 325 product is used in ceramic sector formulations with constant requirements for whiteness and thermal behaviour, ensuring stability in the production process. As a calcium silicate, wollastonite supplies lime and silica without releasing gases during firing, which reduces outgassing defects in the glaze and allows cycles to be shortened. Its acicular habit, needle-shaped, also makes it useful as a reinforcing filler in paints, plastics and friction materials.

The product is supplied in 25 kg bags and big bags, with delivery schedules and volumes planned according to the operating requirements of each production facility.

  • Frequently Asked Questions

Frequently Asked Questions About the Wollastonite

What advantage does wollastonite have over other sources of calcium?

That it releases no gases on firing. A carbonate gives off CO₂ as it decomposes, and that outgassing can cause pinholing and porosity in the glaze. Wollastonite is already a silicate, so it supplies lime and silica without generating gas, which allows faster firing cycles.

Because of its acicular habit: its particles are needle-shaped rather than equidimensional. That geometry means they act as a reinforcement within the matrix, improving the mechanical strength and dimensional stability of paints, plastics and friction materials.

In the usual nomenclature for ground raw materials, that figure refers to the reference mesh of the material. To find out the specific characteristics of the GLAZE 325 grade as they apply to your process, please contact us and we will provide the product’s technical documentation.
