Abstract

This paper reports the results of investigation on the new composition for flameless heaters based on aluminum powder and on alkali metals. Aluminum was chosen as the main ingredient of the powder mixture. Aluminum is a high density energetic material. The nanopowder of aluminum obtained by mechanical activation. The mechanical activation of powder materials removes them from an equilibrium state, which determines their unusual properties. Mechanochemical treatment of powders was carried out in the laboratory planetary mill (activator of 2013, rotation speed - 100 rpm, power - up to 0.55 kW) provided by PARITET company. The surface structure and morphology of activated nanopowder were demonstrated in the article by scanning electron microscopy (SEM). The components of the exothermic composite (CaO: Na2CO3: Al) were obtained in various ratios and the optimal compositions of flameless alkali metal heaters were determined. The dependences of temperature on the time of oxidation of exothermic mixtures are shown.
