Abstract
A monolithic ceramic body with ordered pores and a method of making a monolithic ceramic body is provided including applying a fugitive material in a pattern having a predetermined order, size, shape, orientation and location to a broad surface of at least one layer of green ceramic material. A second ceramic layer is juxtaposed in a stack with the first layer, with the fugitive material between the layers. The juxtaposed layers are laminated and the stack is heated to a first temperature to dislodge the fugitive material and provide a plurality of pores having a predetermined order, size, shape, orientation and location which matches that of the fugitive material pattern. The stack is then heated to a second temperature to form a monolithic ceramic body which includes the pores.
