Effect of polymorphic phase transformations within an alumina layer on the ignition of aluminum particles
Experimental measurements of aluminum ignition temperature and models used to describe aluminum ignition are reviewed. It is shown that the current models cannot describe ignition of aluminum powders of different sizes and ignited under various experimental conditions. The properties of and phase …

Characterization of aluminum powder ignition
Heating rate effect and particle size effect on ignition temperature of Al powder were studied to collect data for development of a possible Al powder ignition model. Aluminum ignition is associated with a highly accelerated burn rate and high combustion enthalpy. A new ignition model, which can …

Synthesis and characterization of metal-based reactive powders
Aluminum added to propellants, explosives, and pyrotechnics, boosts their energy density. Different approaches were investigated that could shorten aluminum ignition delays, increase combustion rates, and decrease the tendency of aluminum droplets to agglomerate. Here, Al-based reactive, …

High temperature spectroscopic measurements of aluminum combustion in a heterogeneous shock tube
Aluminum is an important energetic material that burns with a variety of oxidizers with a high reaction enthalpy. It is a top performer for energy density if oxidizer mass is considered as well as the fuel. Because of this, it is often used as an energetic additive in anaerobic conditions because …
