ABSTRACT:
A ceramic, in particular refractory product is provided comprising a matrix material which contains pores and where the pores are obtained by driving off of opening materials. The product is characterized by pores which are of a flattened shape resulting from platelet shape or flake shape voids. The invention further provides a method for the production of the ceramic product, where a platelet shaped opening material is admixed to the ceramic raw material. The resulting products are characterized by advantageous strength and thermal insulation properties.
