Abstract
Reactive aluminium (Al) powders, which are used in propellants and explosives, require the active support of strong oxidizers to break Al oxide layer and better surface thermochemical reaction. Considering this, current work demonstrates the improved ignition and combustibility of the recycled Al powder modified with various fluorinated and polyphenolic interfacial layers and reactive metals. The better activity was owned by the Al@PD/TA/Fe sample. The DSC result of the Al@PD/TA/Fe sample revealed the oxidation of PVDF at 341.56 °C and surface oxidation of Al at a temperature of 426.81 °C. The decomposition of fluoropolymer at lower temperature facilitated the prompt surface oxidation of Al followed by efficient rupture of the oxide layer which promoted the pre-ignition reaction of Al. Based on the results, combustion mechanism has been proposed. The ignition test of the Al@PD/TA/Fe sample has shown the rapid ignition luminous streaks and claims its potential candidature for solid fuel application.
期刊介绍:
Powder Technology is an International Journal on the Science and Technology of Wet and Dry Particulate Systems. Powder Technology publishes papers on all aspects of the formation of particles and their characterisation and on the study of systems containing particulate solids. No limitation is imposed on the size of the particles, which may range from nanometre scale, as in pigments or aerosols, to that of mined or quarried materials. The following list of topics is not intended to be comprehensive, but rather to indicate typical subjects which fall within the scope of the journal's interests:
Formation and synthesis of particles by precipitation and other methods.
Modification of particles by agglomeration, coating, comminution and attrition.
Characterisation of the size, shape, surface area, pore structure and strength of particles and agglomerates (including the origins and effects of inter particle forces).
Packing, failure, flow and permeability of assemblies of particles.
Particle-particle interactions and suspension rheology.
Handling and processing operations such as slurry flow, fluidization, pneumatic conveying.
Interactions between particles and their environment, including delivery of particulate products to the body.
Applications of particle technology in production of pharmaceuticals, chemicals, foods, pigments, structural, and functional materials and in environmental and energy related matters.
For materials-oriented contributions we are looking for articles revealing the effect of particle/powder characteristics (size, morphology and composition, in that order) on material performance or functionality and, ideally, comparison to any industrial standard.
