Abstract

Abstract: Cr nanometer powder with mean diameter 50 nm was prepared in an organic solution of CrCl₃, using sodium triethylborohydride as a reducing agent, toluene as a solvent, PVPas a dispersant, PdCl₂as a nucleator. The temperature, the concentration of reactants and the addition of dispersant and nucleator were the main factors affecting the particle size. Also the mechanism and thermal stability of Cr nanometer powder were discussed.

Key words: Preparation of Cr nanometer powder, Dispersant, Nucleator, Thermal stability
