<p>In the method for manufacturing slabs of ceramic material which envisages preparation of an initial mix comprising ceramic sands with a grain size of less than 2 mm, preferably less than 1.2 mm, a binder and the so-called filler namely mineral powders chosen from feldspars, nephelines, sienites, mixed with clays and/or kaolinites, which powders after firing form a continuous ceramic matrix, deposition of the initial mix on a temporary support for the compaction step by means of vacuum vibrocompression, drying and firing, a binder consisting of an aqueous dispersion of colloidal silica called silicasol is used.</p> |
