Abstract

The invention relates to a ceramic filter with open-celled foam structure based on high-melting ceramic for the filtering of molten metals, having two opposite through-flow faces, running transversely to the direction of through-flow of the molten metal, and at least one side face, extending essentially in the direction of through-flow, an organic foam material being impregnated with a high-viscosity ceramic slip, then, after drying, the foam material removed by heating and the remaining ceramic material calcined, as well as a process for its production. In order to achieve an increased mechanical and thermal stability, it is provided that the side face(s) are provided with a closed layer of refractory material of a depth of 0.5 to 3 mm over at least 50% of their length in circumferential direction essentially symmetrically on opposite sides and preferably entirely, and the free cell membranes of the foam structure at the through-flow faces are closed by a coating of refractory material.
