Definitions

  • the cobalt ammine complex aqueous solution needs to be salted to cause an electrolysis reaction.
  • this salt it is preferable not to cause electrolysis within the range of applied voltage for depositing coba-alto-nanodendrites, but it is not limited, but for example, Li SO, Na SO , NaCl, NaBr, NaNO,
  • cobalt aqueous solution of cobalt ammine complex was electrolyzed to deposit cobalt nanodendrites, and the cobalt oxide nanodendrites were baked in an electric furnace to form cobalt oxide fine particles.

Abstract

L'invention concerne un procédé de fabrication d'une nouvelle fine particule d'oxyde de cobalt. L'invention concerne notamment un procédé de fabrication d'une fine particule d'oxyde de cobalt, ledit procédé comprenant une étape de traitement thermique d'un nanodendrite de cobalt. L'étape de traitement thermique d'un nanodendrite de cobalt est de préférence réalisée par traitement thermique dans un fourneau et la température de traitement est de préférence supérieure ou égale à 200 °C mais inférieure ou égale à 1 495 °C et la durée de traitement est de préférence supérieure ou égale à 5 minutes mais inférieure ou égale à 2 heures. Le nanodendrite de cobalt peut être obtenu par électrolyse d'une solution aqueuse d'un complexe d'amine de cobalt.
