Highly porous ceramic material for absorption and adsorption purposes, particularly for animal litter/bedding

摘要

Highly porous ceramic material for adsorption and absorption purposes, particularly 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-value in the range 5 to 9, preferably 7 to 8; a bulk density of 400 to 700 g/l; an internal surface (BET-N.sub. 2) between 20 and 200 m.sup.2 /g, preferably between 80 and 150 m.sup.2 /g; which can be produced by firing a foamed mixture of clay or clays, optionally aggregate or aggregates, anionic or cationic surfactant or surfactants and deflocculant or deflocculants, process for the production thereof and use thereof.
