Closed-pore cellular aluminum was experimentally made using recycled commercial post-consumer aluminum containers as an extremely fine powder (below 32 µm) and calcium carbonate (CaCO3) as a foaming agent, replacing the much more expensive titanium hydride (TiH2) frequently used. The aluminum powder was processed by the own original method of microwave melting and atomizing by contact with nitrogen jets. The mixture foaming was performed by irradiation heating in microwave field at 750 °C. The main characteristics of aluminum foam specimens (apparent density in the range of 0.88-1.10 g·cm-3, heat conductivity between 3.30-5.65 W·m-1·K-1, compression strength within the limits 3.9-7.4 MPa, and homogeneous microstructure with cell size below 0.45 mm) were almost similar in terms of quality with products made with TiH2.
