ABSTRACT:
A fluid-permeable article which permits fluid to pass therethrough includes a porous ceramic structure having a multiplicity of hollow members made of ceramic material which are concatenated with each other to form a framework having a continuous capillary passageway system. A continuous space is formed outside of the framework and is defined by the outer surfaces of the hollow members. A continuous matrix material fills the continuous space outside of the framework and cooperates with the porous ceramic structure to provide an integral composite structure consisting of the ceramic material and the matrix material. The continuous passageway system is open in at least a portion of the exposed surfaces of the article and permits fluids to pass therethrough.
