At Imerys Refractory Minerals we produce mullite-based chamottes for sanitaryware and ceramics floor tiles production, but also clays used for their ideal deflocculation in sanitaryware, tiles and Kerphalite™, as zircon substitute in glazes and opacifiers.
Mullite offers shrinkage control and controlled thermal expansion and enhances the mechanical strength and whiteness of a ceramic body.
Our products are an ideal fit with the Imerys Ceramics portfolio, and are distributed through the Imerys Ceramics sales team.
For sanitaryware ceramic applications, adding chamotte to the mixture can prevent distortion during firing, allowing the production of bigger and more complex pieces.
The tile industry also uses chamottes for extruded tiles in particular.
Our brand portfolio is comprised of the well-known Mulcoa®, Clayrac™ and CHK™ lines.
Our Clayrac range of sanitaryware chamotte is comprised of:
A very high-quality chamotte – Clayrac épurée
An affordably-priced chamotte – Clayrac SMD, offering suitable quality for many applications
