Animal litter and process for producing it

A plant substrate, characterized by the fact that it contains 20 to 100% of a granulate consisting of foamed clays or weakly fired ceramic materials, as well as the use thereof.

Plant substrate and use thereof

Plant substrate and uses thereof

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.

Highly porous ceramic material for absorption and adsorption purposes,

Lightweight ceramic material for building purposes, particularly for bricks, plates and panels, as well as for using as an aggregate/filler material for lightweight building materials, characterized by a porosity of 50 to 300%, preferably 100 to 250%; a pH-value between 5 and 9, particularly 7 to 8; a bulk density of 300 to 700 g/l; which can be produced by firing a foamed mixture of clay or clays, optionally aggregate or aggregates, anionic or cationic surfactant or surfactants, deflocculant or deflocculants, and optionally a hydraulic binder, such as cement, at temperatures above 600.degree. C., process for the production thereof and the use thereof.
