Clays for sanitary ceramics

Clay materials play a key role in the production of sanitary ceramics such as washbasins, toilet bowls, bathtubs and other products. These materials provide ceramic products with strength, plasticity and the ability to be shaped into the desired shapes. In addition, they contribute to the aesthetics and functionality of the final products. The high content of clay minerals with a layered structure allows water absorption, which is key to ensuring the necessary stability during drying and firing processing.

Physical properties

  • Plasticity allows the material to be easily shaped into the desired shapes. This property is a result of the clay's ability to absorb water and form bonds between particles.
  • The porosity of clay materials ensures that water can be easily removed during drying and firing, which prevents cracking and deformation.
  • Clay materials ensure high strength of the final ceramic, which is key to resistance to mechanical wear.
  • Sanitary ceramics must withstand high temperatures during firing. Clay materials provide thermal stability, which minimizes the risk of deformation.

Packaging and shipping

  • Dry, crushed or micro-ground
  • Loosely packed, in paper bags of 40 kg (20 pcs per pallet in shrink film), in big-bags of approx. 1 ton per pallet.
  • Shelf life is unlimited in a dry environment.
  • Since this is a natural product, slight deviations from the values ​​stated in the technical documentation are possible.
