Abstract
A reversible chlorine electrode which may be used in molten salts up to temperatures of at least 900°C is described. Chlorine gas is forced through a porous graphite cylinder in contact with the solution under study. The electrode was tested in the Ag|AgCl|Cl2 (graphite) cell and an exactly linear dependence of emf on temperature was found for the temperature range 530 to 920°C. Excellent agreement with earlier emf measurements at temperatures below 600°C was found and the results indicate that the calculated values based on thermal data at high temperatures are high. Emf values for the cell from 530 to 920°C are given.Keywords
