Notes:
Recently, a novel processing route for fabricating microcellular ceramics has beendeveloped. The strategy for making the microcellular ceramics involves: (i) forming some shapescontaining a mixture of preceramic polymer, expandable microspheres and optional fillers by aconventional ceramic forming method, (ii) foaming the compact by heating, (iii) cross-linking thefoamed body, and (iv) transforming the foamed body into microcellular ceramics by pyrolysis. Theflexural strength and compressive strengths of the microcellular ceramics were investigated; valuesup to 30 MPa and 100 MPa, respectively, were obtained at room temperature. The superiormechanical properties were attributed to homogeneous distribution of cells in microcellular ceramics
