Abstract


Open cell aluminum (Al) foams are developed in this work by a novel direct foaming process in which a low concentrated alkane phase is emulsified in a stabilized Al powder suspension. In this versatile technique, the porosity parameters are adjusted during foaming of the emulsified suspensions and the final stability is achieved by a thermal treatment above the melting temperature of Al. The thin oxide layers surrounding the Al particles and the ascertained percolation of the molten metal are essential in this stage. The efficiency of the processing route is demonstrated with the essential requisites for successful foaming and the final structural stability. Furthermore, open cell Al-foams/zeolite composites exhibiting a hierarchical porous structure (nano-and macroscale) are produced by hydrothermal synthesis of Faujasite-like zeolite on the surface of the developed AI-foams. Due to the advantageous properties of zeolite X in N(2) adsorption, the application of the composites for separation of N(2) from air is specially envisaged.
