In this paper, a new method of preparing open cell aluminum foam by Low-Pressure Infiltration and calcium oxide particles has been developed creatively. By means of X ray microscopic analysis, it can be seen that mixed grout mixed with anhydrous ethanol and calcium oxide powder in the particles reduces the porosity of the compact structure and makes the connection between grains more closely. The porosity can be accurately controlled by the mass-volume direct calculation method of porosity. Calcium oxide particles in particles and aluminium complexes can be quickly removed by using ammonium chloride aqueous solution heated above 70 C. According to the requirement of sound absorption coefficient test, three kinds of test samples of porosity were prepared.
