This paper presents the results of studying the chemical compatibility of nanopowders of metals and their oxides with the components of energy materials (EMs). It is shown that nitroester and nitrile compounds would not be appropriate for use in the development of EMs containing nanopowders of metals and their oxides. Classes of substances which possess acceptable compatibility with nanopowders of metals and their oxides are determined. © 2013 Pleiades Publishing, Ltd.

The thermally reversible processes of melting and crystallization of the [1,2,5]oxadiazolo[3,4-e][1,2,3,4]tetrazine-4,6-dioxide–2,4-dinitro-2,4-diazapentane equimolar molecular complex produced in various technological modes of its isolation from the melt are studied and optimized by using turbidimetry, optical microscopy, and differential scanning calorimetry. The kinetic factors of the stepwise crystallization of the complex related to both the formation of nucleation sites and growth of the crystals are identified. A colorimetric method for controlling the phase purity and evaluating the content of impurities in the molecular complex after their preliminary identification by infrared spectroscopy is developed. © 2015, Pleiades Publishing, Ltd.

Results of an investigation into the impact of metallic and nonmetallic nanodispersed powders on the parameters of combustion of mixed energetic materials (EMs) based on ammonium nitrate are presented and compared with micropowders. The catalytic activity ranks of the powders are plotted showing their effect on the combustion characteristics of nitrate materials. It is shown that the high efficiency of nanoaluminum is caused by the presence of γ-Al2O3 powder particles on the surface. © 2014, Pleiades Publishing, Ltd.
