Generation of Nano-copper Particles through Wire Explosion Method and its Characterization

P.K. Dash and Y. Balto

Nano-copper particles are produced in argon gas ambience by the controlled-current wire explosion process. Physico-chemical diagnostic studies, like Wide Angle X-ray Diffraction (WAXD), Thermo-Gravimetric Differential Thermal Analysis (TG-DTA) studies, Energy Dispersive Analysis by X-ray (EDAX) are carried out. The surfactants in the electrolyte served as both a templates and stabilizers during the synthesis procedure The Wide Angle X-ray Diffraction measurements have shown that nano-copper particles prepared by the process are mainly composed of (111), (200) and (220) orientation crystallites and also revealed all relevant Bragg’s reflection for FCC crystal structure of copper metal. The particle size obtained through Scherrer’s equation is about 36.34 nm. Fourier Transform Infra-Red (FTIR) test, HRTEM and Scanning Electron Microscope (SEM) studies confirmed the nano size of the particles in spherical shape with FCC structure of the copper particle. Also, the crystalline structures of the Cu nano particles were confirmed by the Wide Angle X-Ray Analysis results. The current density applied during the electro-deposition has an effect on the shape and yield of the copper nano-particles.
