The aim of this work consists in the charaterization of mechnical properties (compressive law of behaviour and elastic properties) of a ceramic foam whose pore volume fraction is about 87%. Compressive behaviour is similar to these of cellular materials (elastic domain, plateau phase and densification successively). Elastic properties determined by 3 different methods (i-from the law of behaviour, ii-by pulse echography technique and iii-by impulse excitation vibration) have shown that the mean value of overall Young’s modulus is in agreement with Ashby’s models of prediction considering the interconnectivity of pores in the microstructure of tested materials.
