Abstract: | The reaction of sodium, calcium, and zinc chlorides with atmospheric oxygen in the presence of transition metal oxides and
antimony oxide at temperatures exceeding the melting temperatures of chlorides was studied. The content of chorine, product
of oxidation of chloride ions in molten NaCl and CaCl2, was determined as a function of the polarization force of cations of transition metal oxides. |
