Abstract
Process for making graded porosity ceramics. A process for making graded porosity ceramics is described which includes the steps of placing a chosen amount of ceramic powder into a mold, compacting the ceramic powder into a green body, applying at least one sintering aid precursor to at least one chosen surface of the green body, allowing the at least one sintering aid precursor to penetrate the at least one surface within a chosen volume of the green body, heating the green body, whereby the sintering precursor generates a sintering aid, and hot pressing and sintering the heated body at a temperature whereby the green body is transformed into the sintered ceramic object.
