During the reactive synthesis of porous materials contained Al, the heat emission from aluminothermic reactions should be carefully controlled so as to avoid the initiation of Self-propagating High-temperature Synthesis (SHS) reactions [32], [33], because the occurrence of SHS reactions can lead to the ravages of apparent shape and microstructure of sinters. Therefore, the exothermic behaviors were first studied. As shown on the DSC curves in Fig. 2, the compacts of Fe/Al and Fe/Al/Cr elemental

B2-structured Fe-20.5Al-18Cr (wt.%) intermetallic filter material developed for high-temperature coal-gas purification was fabricated by reactive synthesis using blended Fe/Al/Cr powders. This method addresses the problems presented in the manufacture of porous Fe-Al-Cr materials with high content of Al, making the production more convenient, flexible and controllable. The exothermic effect, volume swelling, pore formation and diffusion reactions during the reactive synthesis of porous Fe-20.5Al-18Cr were investigated systematically. A comparat...
