Abstract： In order to study the static and dynamic property of ceramic foam, quasi-static uniaxlal stress compression tests, quasi-static uniaxial strain compression tests and dynamic SHPB tests were conducted for a new kind of closed-cell clay ceramic foam due to its good performance in energy-absorption, anti-blasting and potential prospect in engineering. Stress-strain curves of the ceramic form at three different conditions mentioned above were obtained and the strength, deformation, and failure behavior of the material were discussed. The results indicated that: (1)the ceramic form is a strain rate sensitive material; (2)Although the elastic limit of the ceramic form is not as large as normal ceramic but the strength keeps at a certain value after the peak stress reached; (3) ceramic form has large extreme strain both in static and dynamic loading and its energy lose related to the irreversible deformation due to pore collapse in the material in a loading-unloading cycle is considerable, and hence the effects of the wave absorption and energy dissipation are prominent. It is suggested that the ceramic form can be considered as one of the important material for defense components in engineering
