Oxidation of Aluminum Particles from 1 to 10 nm in Diameter: The Transition from Clusters to Nanoparticles

Oxidation of Aluminum Particles from 1 to 10 nm in Diameter: The Transition from Clusters to Nanoparticles

Micrometer- and nanometer-scale aluminum (nAl) particles are often considered attractive choices for fuels in energetic materials. In general, reaction rates increase as particle size decreases because of the increased surface area and reduced diffusion lengths between reactants. The oxidation behav...

Zusammenfassung:Micrometer- and nanometer-scale aluminum (nAl) particles are often considered attractive choices for fuels in energetic materials. In general, reaction rates increase as particle size decreases because of the increased surface area and reduced diffusion lengths between reactants. The oxidation behavior for aluminum nanoparticles >10 nm in diameter has been widely studied, and so has the oxidation behavior of clusters
