Plates of ceramic material are prepared starting from stone material, particularly feldspar, quartz, porphyry, granites, silica, syenites, nephelines, ceramic materials, clays, kaolins, bentonites, in granular and/or powder form, mixed with a small amount of ceramic binder to form a mixture. This mixture is distributed onto a plane delimited from a containing frame and then subjected to the simultaneous action of a vacuum and of a vibratory motion combined with a pressing action. After the moulding step, a drying step and then a firing step are carried out, the latter taking place at the standard temperatures for the manufacturing of ceramic products. The resulting plate has high mechanical properties, is highly resistant to atmospherical and chemical agents, and has a very valuable aesthetic appearance.
