Preparation and characterization of zinc nanoparticles: Ball milling and Hall-Williamson method

The preparation of Zn nanopowder using high-energy ball milling has been studied. In an argon-free setting, Zn powders were ball milled. X-ray diffraction measurements have been used to classify the milled powders. X-ray powder diffraction was used to investigate lattice strains in milled Zn powders. The Bragg reflections' half-widths and integrated intensities are used to calculate the lstrain and Debye-Waller factor (B). With increasing lattice strain, the Debye-Waller factor increases. The effective Debye-Waller factors for Zn have been determined based on the association between strain and effective Debye-Waller factors. The effect of lattice strain on the energy of vacancy formation has been calculated. (c) 2021 Elsevier Ltd. All rights reserved.
