At Imerys Refractory Minerals we produce mullite-based chamotte for sanitaryware and floor tiles production, but also clays used for their ideal deflocculation in sanitaryware and tiles and Kerphalite™, as a zircon substitute in glazes and sopacifiers.

Our products are an excellent fit with the Imerys Ceramics portfolio and are distributed through Imerys Ceramics sales team.

Mullite offers the control of the shrinking control and controlled thermal expansion and enhances the mechanical strength and  whiteness of a ceramic body.
Our Mulcoa® product is a high alumina mullite-based chamotte with alumina content going up to 70%.
Mulcoa range

Molochite™ is widely used as filler for the production of glazes and engobes. Freedom from contamination and accurate control of  physical and chemical properties make Molochite the ideal choice for high quality end products.
Technical data sheets available on demand.

Kerphalite KF is a natural source of alumina and mullite which can be profitably used when better control your ceramics support’s physical and chemical properties is required.
Due to its high purity and very fine particle size distribution, micronized Kerphalite KF is an efficient and economical alternative to zircon silicate as an opacifier for glazes and engobes.
