Abstract

Nano-sized nickel powders were prepared through a wet chemical reduction, of NiCl 2 by sodium in liquid ammonia at -45 °C, and a subsequent heat-treatment in vacuum at 300 °C. The prepared product was systematically characterized by X-ray diffraction (XRD), scan electron microscopy (SEM), transmission electron microscopy (TEM), and BET specific surface area measurement. The results show that the product was composed of nano-sized nickel particles, with average particle diameter of about 20 nm, and specific surface area of about 30 m 2g -1. The possible formation mechanism of the nano-sized nickel powder was also discussed briefly.
