Foam ceramics have excellent properties such as high porosity, high temperature resistance, chemical corrosion resistance and good thermal stability, and are widely used as metal liquid filter, high temperature gas and ion exchange filter, catalyst carrier, environmental material, heat insulation material, sound absorption material, biological material and so on. In this paper, the preparation technology of porous ceramic materials is investigated firstly. Then the foam ceramic samples with different porosity of Al2O3 and SiC materials were manufactured, and their acoustic properties were tested, and the influence of material and porosity on sound absorption performance was analyzed.
