Highly porous ceramic body for adsorption or absorption purposes, in particular for animal litter, characterized by a porosity of 50 to 300%, preferably 200 to 250%; a water absorption capacity of 50 to 200%, preferably 100 to 150%; a pH in the range from 5 to 9, preferably 7 to 8; a bulk density of 400 to 700 g / l; an inner surface (BET (N2)) between 20 m 2 / g and 200 m 2 / g, preferably between 80 and 150 m 2 / g; can be produced by firing a foamed mixture of clay (s), optionally aggregate (s), anionic (s) or cationic surfactant (s) and liquefying agent (s), process for its production and its use. |
