摘要： The invention relates to the field of ceramics and concerns an open-cell expanded ceramic which may be used in the form of a deep-bed filter, and a process for the production thereof. The object of the invention is to produce an open-cell expanded ceramic by a simple and economical process. The object is attained by an open-cell expanded ceramic in which the inner cavities, cracks and the porosity of the ceramic members are filled partially or completely by one or a plurality of metal and/or ceramic phases and/or glass phases. The open-cell expanded ceramic according to the invention is also produced in that during or after sintering the cavities, cracks and the porosity of the ceramic members are partially or completely filled with a melt or a suspension which melt below the melting temperature of the expanded ceramic, have a coefficient of expansion similar to the coefficient of expansion of the expanded ceramic, and a very good wetting capacity, and only react partially or not at all with constituents of the expanded ceramic.

摘要： Substantially dry, self-hardening, thermally activated refractory compositions, suitable for use to produce linings for furnaces or metallurgical vessels such as ladles, tundishes or launders, comprise particulate refractory material, an inorganic binder having associated therewith chemically or physically bound water such as sodium metasilicate pentahydrate or tribasic sodium phosphate dodecahydrate, and an element or compound, such as aluminium, which will react exothermically with the inorganic binder. The compositions may also contain an inhibitor such as a mineral oil or a vegetable oil to inhibit premature exothermic reaction.
