Preparation and Characterization of Nano-Ni/B Composite Particles

Abstract:

The synthesis of nano-Ni/B composite particles was studied by diamine hydrate reducing nikel chloride in the water bath at 50 °C, in which nano-Ni was made to cover the surface of micron boron powder. The particle size, the structure and properities of the nano-Ni/B composite particles were characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD). And the thermal stability of nano-Ni/B composite particles was studied by employing thermogravimetry (TG), differential thermal analysis (DTA). The results showed that this method could prepare the compact coating for Ni/B particles. The nano-Ni particles coated on boron particle were uniform and continuous. The average diameter of Ni crystallites was about 21.7 nm. Compared with boron powders, the high temperature of exothermic peak of nano-Ni/B composite particles was decreased about 36 °C. The thermal chemistry behavior of the as-prepared nano-Ni/B composite particles was better than superfine boron powders.
