OFFENZELLIGE SCHAUMKERAMIK MIT HOHER FESTIGKEIT UND VERFAHREN ZU DEREN HERSTELLUNG |
摘要 |
<p>The disclosed 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 primary object is to produce an open-cell expanded ceramic by a simple and economical process. This 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 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.</p> |
