Chamotte for ceramics

Chamottes for FC, FFC and SFFC sanitaryware bodies

Chamotte is calcined clay produced by firing selected fire clays at high temperatures, then grinding and screening to specific particle sizes. 

In ceramic body formulations, chamotte functions as a structural component that:

• reduces shrinkage during drying and firing
• limits deformation
• enhances mechanical strength
• improves dimensional stability

These functions are especially valuable in sanitaryware applications, particularly in the production of Fire Clay (FC), Fine Fire Clay (FFC) and Super Fine Fire Clay (SFFC) bodies, where large and complex-shaped pieces require stable and reliable performance.
