Abstract

Process for the fabrication of baked ceramic insulating pieces, according to which a uniform paste is prepared which contains in suitable proportions water and clay and/or kaolins containing or to which substances are added which by the action of drying, heat or of the combustión disappear, totally or partially burnt and causing gaps in the baked mass, and/or granulates or fines of expanded materials, of light aggregates and/or unexpanded normal aggregates, obtained naturally or artificially, with the possible addition of foaming and blowing agents, fluxes and fibrous substances or binders, and substances that by chemical reaction produce volume increase, independent or contained in the clay or kaolin; this paste is poured, without the aid of vacuum or pressure of any kind, into special molds prepared for this purpose, dimensioned in such a way that blocks of appropriate dimensions can be obtained to be subdivided by sawing, obtaining essentially from each block more than one piece, equipped with the exact final dimensions required; the blocks are demolded, dried conveniently and cooked at the appropriate temperatures to the clays, kaolins and other substances added, in order to achieve the adequate consistency and resistances; and, in final operation, the blocks obtained in the exposed form are divided by sawing, obtaining from each block more than one piece equipped with the exact dimensions required for its shipment to the market and its direct application to the work.
