Synthesis of Cobalt Nanopowder Using Surfactants of Different Nature

Abstract:

The synthesis of controlled dispersity nanopowders is a vital nanotechnology task. This paper describes how the type of surfactants used during the hydroxide precursor Co (OH)₂precipitation influences the dispersity of cobalt nanopowder obtained by the process of hydroxide reduction. It has been determined that the usage of surfactants may both increase and decrease the nanopowders dispersity: when using 0.1 wt.% “cetylpyridinium chloride – no surfactants – EDTA sodium salt – polyethylene glycol – sodium lauryl sulfate” surfactant solutions, during the precipitation process the specific surface of the obtained metallic nanopowder was equal to “3.7 – 4.5 – 5.0 – 6.0 – 9.5 m²/g”, respectively.
