Studies on the preparation of Cr nanometer powder

Cr nanometer powder with mean diameter 50 nm was prepared in an organic sol ution of CrCl3, using sodium triethylborohydride as a reducing agent, tolue ne as a solvent, PVP as a dispersant PdCl2 as a nucleator. The temperature, the concentration of reactants and the addition of dispersant and nucleato r were the main factors affecting the particle size, Also the mechanism and thermal stability of Cr nanometer powder were discussed.
