Synthesis and Investigation of Nickel Nanoparticles

Abstract

The melting point is one of the most important thermodynamic properties of metallic materials. The melting point, that characterizes the bulk material is independent of the size in the microscopic range but will be size-dependent in the nano-range. The reason of this phenomenon is the high surface to volume ratio, thus the atoms situated on the surface play a greater role. One of the objectives of our research was to synthetize nickel nanoparticles (Ni NPs) using aqueous medium technology. The analysis of the produced particles was performed by X-ray diffraction (XRD) and Scanning electron microscopy (SEM). Furthermore, the main objective of our work was to determine the size dependence of the melting point of the produced nickel nanoparticles by differential scanning
