| Abstract: | Cr nanometer powder with mean diameter 50 nm was prepared in an organic solution of CrCl 3, using sodium triethylborohydride as a reducing agent, toluene as a solvent, PVP as a dispersant, PdCl 2 as 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. |
