The microstructural SEM measurements of alumina foams were compared with X-ray micro tomography investigations also on the pore network. Young's modulus of alumina foams was determined by impulse excitation and ultrasonic sound velocity measurements. These two independent techniques showed similar results. Gibson and Ashby's model of completely open-cell and closed-cell foams was compared with experimental data from compression tests. The thermal conductivity measurements using laser-flash analysis were correlated with the pore network in the alumina foam structure.
