| Abstract |
We used Sn-58Bi and Cu wires to investigate the effects of variable conditions (such as pressure and wire diameter) on the formation of three-component nanoparticles. In the synthesis of the three-component nanoparticles, pulsed wire discharge was used to sublimate the wires. In this system, the K factor is described as Ec/Es, where Ec and Es are respectively the applied energy and the sublimation energy of the system. Experiments were conducted in a N2 atmosphere using the following parameters: voltage of 6 kV, pressure of 50-100 kPa, and Cu wire diameters of 0.1 and 0.2 mm. X-ray diffraction and field emission scanning electron microscopy were employed for structural analysis, particle size distribution analysis, collection rate, and composition studies of the nanoparticles.
