<p>A porous granular ceramic material has a granule size of from 1 to 5 mm, a bulk density of from 200 to 700 g/l, preferably 350 to 550 g/l, a porosity of from 50 to 80% v/v, preferably from 65 to 80% v/v, and a liquid absorbency of from 20 to 200%, preferably from 40 to 150%, of water based on the weight of the grannular material. The material may be made by calcining a mixture of a clay and a particulate combustible material. The material is suitable for use as animal litter or as an industrial absorbent for liquids.</p> |
