Mineral range

We have a broad portfolio of mineral resources and processing plants throughout the world which allow us to match the right mineral to each type of technical ceramics body type.

Each mineral plays a crucial part in the performance of the final part:

Ball clay

Our extensive range of ball clay products provide:

  • High plasticity and unfired modulus of rupture to allow the shaping of complex items while reducing breakage
  • Low alkali values in alkali preventing  chemical digestion of the cordierite phase
  • Low Al2O3 values to boost steatite forming phase
  • High Al2O3 values to boost cordierite forming phase


Imerys kaolin present the following properties: 

  • Low rates of free quartz particles
  • Low alkali values in alkali preventing  chemical digestion of the cordierite phase
  • Low to extremely low alkali values in alkali to decrease flux phase in alumina bodies
  • Suitable particle size to optimize particle packing


With their low magnetic content, Imerys chamotte for cordierites provide:

  • Low firing shrinkage
  • Low coefficient of thermal expansion
  • Improved casting properties

We are also a leading supplier of kiln furniture solutions for technical ceramics production.
