“…[9,12]. Nevertheless, complex components [13][14][15] or metal nanopowders [16][17][18] show good catalytic activity for the conversion of cyclic nitramines during combustion. Nano-sized metal powders (or metal nanopowders, n-Me) have a stronger effect on the propellant's burning rate in comparison with other catalysts [19].…”

The paper investigated the effect of metal nanopowders additive on the combustion properties of HMX/CL‐20/AP/polyvinyltetrazole binder/Al propellants. Using thermal analysis, the authors described the effect of aluminum, boron, zinc, nickel, copper, and molybdenum and identified the combustion in a pressure range from 4 to 10 MPa with a pressure step of 1 MPa. No significant correlation between the oxidation properties of the n‐Me powders and the combustion properties of propellants was discovered. An addition of nanopowders caused an increase in the propellant burning rate by approximately 30 % for n‐Al, n‐B, n‐Ni, and n‐Mo independent from the pressure values. An addition of n‐Cu resulted in a burning rate increase by a factor of 4.9 due to coppers’ probable catalytic activity during interaction with nitroesters and cyclic nitramines in a solid phase. n‐Zn additive increased the propellant burning rate by factors 2.3 and 3.6 at 4 and 10 MPa, respectively, due to catalytic activity of zinc in a gaseous phase.

“…The regulation of ballistic properties and the burning rate of such formulations are a complex task due to their chemical resistance to the majority of conventional catalysts (metal oxides , stearates , ferrocene , etc.). Nevertheless, nano‐sized metal powders and metal oxides were found to be competitive promoters of HMX, RDX, and CL‐20 decomposition. Thus, they can improve the combustion performance of such propellants in general.…”

“…The complex chemical mechanism of nitramines decomposition and possible interactions between formed gaseous products and metal additives resulted in the domination of quasi‐equilibrium approach for their description. But such experimental works focused only on a very limited number of substances like Al , Cu , Ni , Al 2 O 3 , TiO 2 , Fe 2 O 3 (more detailed review of such studies is provided in Table ).…”

Aluminum powders were comprehensively described as the prospective ingredients of the modern propellants. The paper also studied the influence of micro-and nanopowders of metals (μ-Me and n-Me) and metal oxides (μ-MeO and n-MeO) on the burning process of modern aluminized propellant with HMX, CL-20, AP, and active binder. The following metal additives were used: Al, B, Zn, Ni, Co, and Mo. The effect of the following oxides CoO, V 2 O 5 , MnO 2, and Fe 2 O 3 was studied together with LiF. The combustion tests of modified propellant compositions were carried out in the Vielle bomb in a pressure range 2-10 MPa. n-Me addition resulted in an increase in the burning rate by 10 % for n-B, by 30-40 % for n-Ni and n-Mo in the studied pressure range. The introduction of n-Cu caused a burning rate to increase fivefold. n-Zn additive resulted in increasing of the propellant burning rate by 130 % and 260 % at 4 and 10 MPa, respectively. It was probably caused by the catalytic activity of those metals in the gaseous phase. The effect of complex additive was observed to be insignificant for additives with μ-Co 3 O 4 , μ-V 2 O 5 , μ-Fe 2 O 3 and n-Fe 2 O 3 . The burning rate of propellant with n-CuO additive value was higher by a factor of 4 in comparison with the basic formulation in the studied pressure range.

“…This property of MgAl alloys improves the ability of ignition of gas generators on the basis of AN MgAl [10][11][12][13]. Many studies have declared that the accession of variables of metal oxides in the composition of the energetic materials on the basis of AN improved combustion characteristics [14][15][16][17][18][19]. Although some metal oxides exert a negative effect on combustion of mechanical MgAl alloy in the composition of the composite [20].…”

Ammonium nitrate (AN)-based composite gas generator have attracted a considerable amount of attention because of the clean burning nature of AN as an oxidizer. However, ammonium nitrate-based gas generator has several major problems, namely, poor ignitability, a low burning rate, low energy, and high hygroscopicity. The addition of different transitional metal oxides and MgAl mechanical alloyed proved to be effective in improving the burning characteristics of AN-based gas generator. In this research work, combustion study of different transition metal oxide based on AN/MgAl composites gas generators was studied. Gas generators were combusted at the pressure of 1 MPa, 3 MPa and 5 MPa in the combustion chamber and the burning rates were determined. It was stated that the addition of metal oxides into the composition of the gas generators improves ignition at low pressure and increases the burning rate. The use of the mechanical MgAl alloys as a fuel allowed the ignition of the gas generator at a lower temperature. The method of thermogravimetric/differential thermal analyzer (TG/DTA) was used to investigate the effect of metal oxides addition on the AN/MgAl-based gas generators thermal decomposition characteristics.
