A Feasibility Study to Increase The Activity of Oxides with Oxygen and to Lower the Ignition Temperature of Slurry Metals
Abstract
The main objective was to commence with the investigation on the influence of doping and of pre-exposure to gamma ray radiation on the reversible oxidation-decomposition reactions of cobalt oxide, Co3O4 yields reversibly 3CoO + 1/2 O2. The principal experimental techniques used were differential thermal analysis (DTA) and thermogravimetrical analysis (TGA). The results indicate that doping cobalt oxide with foreign cations can significantly alter its high temperature chemical reactivity characteristics. Li(+) ion is especially effective as a doping agent to decrease the decomposition reaction temperature and increase the reaction rate. In some cases such as where the oxide is doped with Li(+) or Ag(+1) ions the oxidation or decomposition reaction appears to occur in two steps.
