New economically viable alloys have been developed that exclude the use of scattered non-ferrous metals and contain Wood’s, Rose’s and Darcet’s alloys as activator metals. The applicability of Wood’s, Rose’s and Darcet’s eutectic alloys as activating additives for activating aluminum and obtaining efficient environmentally friendly sources of hydrogen production and storage has been theoretically substantiated and experimentally confirmed. The parameters of interaction of aluminum alloys activated with Darcet’s, Wood’s, Rose’s alloys with water are optimized depending on the temperature, the amount of the activating additive in the alloy, and the pH of the water. The X-ray spectral analysis of the alloys was carried out on an X-Ray Innov-X systems spectrometer. The microstructure of the alloy and its oxidatipnr oducts was studied using an energy-dispersiveX-ray scanning electron microscope(SEM/ EDXs using an OXFORD INSTRUMENTS INCA ENERGY spectrometer mounted on a JEOL Superprobe 733e lectron probe microanalyzer at an accelerating voltage of 25 kV and a probe current of 25 nA. Based on the analysis of the microstructure, the phase components of the alloys athe Al grain boundaries were identified. X-ray diffraction analysis of the reaction products of the alloys formed in vario o xidizing media was carried out on an automated DRON-3 diffractometer with CuК radiation, β-filter. Conditions for shooting diffraction patterns: U=35 kV; I=20 mA; shooting θ-2θ; detector 2 deg/min. X-ray diffraction analysis on a semi-quantitative basis was carried out using diffraction patterns of powder samples using the method of equal weights and artificial mixtures. Quantitative ratios of crystalline phases were determined.
