Aluminum-Zinc (Al-Zn) Dust Analyses for Recycling Purposes

摘要

The physical vapor deposition (PVD) process facility at the McAlester Army Ammunition Plant, McAlester, Oklahoma coat 500-lb bombs with aluminum-zinc (Al-Zn). Transmission electron microscopy and electron diffraction technique revealed Zn and Al particles in the dust waste generated by this PVD process. The x-ray fluorescence analyses and selected electron diffraction patter confirmed the presence of Al-Zn particles and their crystal structure. Powder data files and a standard evaporated gold thin film electron diffraction pattern were used to determine the d-spacing of Al and Zn dust particles.
