Chamotte
Chamotte is a calcined clay. The calcination process takes place in a rotary kiln at high temperatures of 1400 - 1600ºC. Sanitaryware pieces are fired at lower temperatures of around 1200ºC, therefore the chamotte is inert at the firing stage and acts like a skeleton to produce ware with lower shrinkage, better cracking resistance and lower deformation.
It is the introduction of chamotte that characterises the production of fine fireclay, which enables the production of bigger and more complex sanitaryware pieces. Fine fire clay is becoming well established in western Europe particularly in the Civita Castellana cluster, near Rome, Italy; it is of growing importance in the sanitaryware world.
AGS, the Imerys Ceramics' chamotte producer
Imerys Ceramics chamottes are produced near Bordeaux, in France by AGS, which is part of the Imerys group. AGS chamottes are well known for their high quality and consistency; offering reduced cracking, shrinkage and deformation of large complex sanitaryware pieces. These raw materials also make it possible to manufacture the most innovative design-driven pieces.
The following properties are of particular importance in chamotte:
Controlled particle size distribution
Minimal cristoballite to avoid dunting, cracking and health & safety issues
Low magnetic content
In consultation with customers our products can be tailor-made to match requirements. We can also provide chamotte in pellets or in milled form.
