Abstract
Ceramic tiles may be prepared employing a process characterized by the addition to the ceramic raw materials of an aqueous slurry comprising a swellable clay of the smectite family, a binder and a water-soluble salt of a monovalent cation. The ceramic raw materials mixed and then subjected to wet grinding to produce a slip. The thus obtained slip is then subjected to spray drying.
