Flame Propagation Behavior of Aluminum Nanopowder in Bulk Layer

Journal of Loss Prevention in the Process Industries, 2021
Abstract The flame propagation parameters of aluminum nanopowder in the bulk layer were investigated. The aluminum nanopowder produced by the method of the electrical explosion of wires used in this study. The aluminum bulk layer was ignited by open flame, heated body, or electric spark.

Oxidation Mechanism of Aluminum Nanopowders

The Journal of Physical Chemistry C, 2015
Aluminum nanopowders, oxidized at different temperatures using thermogravimetric analyses performed in high resolution mode, are characterized in terms of morphology, structure and microstructure. The particle structure is modeled via geometrical considerations that enable the calculation of the variation of specific surface area during oxidation.

Chemical Vapor Synthesis and Characterization of Aluminum Nanopowder

Journal of Power Sources, 2010
Abstract Aluminum is a component in many promising hydrogen storage materials such as aluminum hydride and complex aluminum hydrides. In this research, Al and TiAl 3 -containing Al nanopowders were prepared by a chemical vapor synthesis (CVS) process using Mg as the reducing agent.

Characterization of Aluminum Nanopowder Compositions

Propellants, Explosives, Pyrotechnics, 2002
The thermal behaviour of two different Al nanopowders and a micron-sized Al powder was studied using DSC, simultaneous TG-DTA, and accelerating rate calorimetry (ARC). The results show that the reactivity of Al powder increases as the particle size decreases.

The Production of Porous Aluminum Hydroxide using Aluminum Nanopowder

2005 11th International Scientific and Practical Conference of Students, Post-graduates and Young Scientists - Modern Technique and Technologies, 2005
Aluminum hydroxide is made good use of production of ceramic materials, is applied to catalytic agent production, and is also widespread technical adsorbent, filling material of polymer and others. The application productivity of aluminum hydroxide is depends on method of its production and type of source material. These substances are usually produced

Hazard Characterization of Aluminum Nanopowder Compositions

Propellants, Explosives, Pyrotechnics, 2003
AbstractThe thermal behaviour in air of two Al nanopowders, Alss and Alsstef, a Teflon coated version of Alss, was determined using DSC, TG‐DTA and accelerating rate calorimetry (ARC). Compared to two larger Al nanopowders, for which hazards results have been reported, Alss and Alsstef are less reactive in air, possibly due to the nature of the ...

Thermal Diffusion in Jammed Aluminum Nanopowders

Applied Mechanics and Materials, 2011
Nanoparticles show a variety of size-dependent properties due to the dramatic changes in the ratio of surface area to volume. The characteristics of nanoparticles different from the bulk material make the properties of the powders composed of these nanoparticles attract more attention.

Investigation of combustion of HEM with aluminum nanopowders

Nanotechnologies in Russia, 2010
A number of problems related to the utilization of nanosize aluminum powders as a combustible component of perspective compositions of high-energy materials is considered. The technology of producing nanopowders using the technique of conductor electrical explosion and the method of dispersed powder composition analysis are shown.
