In recent years, it has been reported that adding titanium into reactive thermite composites (such as Al/I 2 O 5 , B/CuO) can improve their combustion efficiency and lower their ignition temperature. However, these authors were only able to point out the complexity of the mechanisms governing ternary thermites reactivity but failed to answer...

Recently, it has been reported that adding titanium into thermite composites can improve their combustion efficiency and lower their ignition temperature. However, the exact role of Ti reaction in such thermites is still unclear. Here, we put focus on in-depth understanding the reaction mechanism of Ti-based thermite by employing...

Unary nanoscale metallic fuels such as Al, Ti, Mg, Zr, and B with an oxidizer have been massively explored in reactive energetic formulations commonly used in explosives and propellants owing to their high combustion energy. While Al has routinely been preferred, its low melting point and the resultant sintering effects curtail the reaction...

Aluminum has demonstrated compelling attributes over decades of research, encompassing affordability, abundance and a high specific energy density when utilized as a fuel in energetic materials such as nanothermites. However, combustion performance of Al suffers from its high ignition point and sintering tendency, the latter being hypothesized...

Aluminum as fuel has demonstrated compelling attributes over decades of research, including affordability, abundance, and a high specific energy density. It stands out as the most extensively studied metallic fuel 1,2 . However, Al faces a challenge in the form of a high ignition point, primarily attributed to the presence of its native oxide....

In this report, we examine the intricate details of the mechanism driving Zr/CuO thermite system, shedding new light on the exceptional reactivity of Zr fuel with oxygen. Magnetron-sputtered Zr/CuO reactive multilayers were deposited, and thermo-physical techniques were employed to characterize the progression of the chemical reaction upon...

This study reports on a new ternary thermite comprising of Al-TiB 2 /CuO multilayers, designed to take advantage of the high ignitability of titanium (Ti), high volumetric density of boron (B), and low melting point of aluminum (Al). Results demonstrate synergetic effects leading to an energetic layer outperforming single fuel counterparts,...

In this study we demonstrate the effect of change of the sputtering power and the deposition pressure on the ignition and the combustion properties of Al/CuO reactive thin films. A reduced sputtering power of Al along with the deposition carried out at a higher-pressure result in a high-quality thin film showing a 200% improvement in the burn...
