Abstract

The present paper presents a facile and low-cost liquid-solid interaction chemical method to prepare pure Ni-Co alloy nanoparticles by reducing NiCl2.6H2O and CoCl2.4H2O with aluminum as a reducing agent at room temperature. This simple and direct chemical method gives particles of Nanocrystalline NiCo alloy powder in aqueous medium.. Compositional analysis showed that the precursor ratio was almost preserved in the Ni-Co alloy powders. X-ray diffraction indicated fcc structure for Ni-Co solid solutions.. Saturation magnetization increases as a function of Co content in Ni-Co alloy and the alloy with high Co content saturates only at a high field. In this work we report promising chemical method for preparation Ni-Co alloy for large scale production with low cost
