Abstract

In this work, we synthesized the alloy of nickel‒copper by thermal treatment in reductive‒flow of hydrated salts based on Ni and Cu used the stoichiometric 3:1 respectively. The methodology proposed is low‒cost, simple, friendly to environment, and obtain a crystalline phase free of contaminants or remnants of reaction with crystal size of 33 nm and particle size of 659 ± 123 x 416 ± 102 nm, the particles exhibit like‒spherical morphology and heterogeneous agglomerates. In addition, we compared the experimental lattice parameters by theoretical reported and calculated by Vegard's law. The results by Vegard´s law suggest that the composition of copper (XCu) in the alloy is different with respect to the phase identified Ni0.76Cu0.24 by XRD database, but this result don’t affect the lattice parameter. The material was characterized by X-ray diffraction (XRD), energy dispersive spectroscopy (EDS), scanning electron microscopy (SEM), and crystal size and copper fraction in alloy was estimated using the Scherrer equation, and Vegard´s law respectively.
