The purpose of this work was to prepare the thermodynamical phase diagram which shows the stability of alkali carbonates under various environments. Several types of phase diagrams were discussed. Then, the log aC-log Po₂ diagram was proposed. The preparation procedures were described to show the stability region of alkali carbonates on the log aC-log Po₂ diagram. The diagram was compared with the well known E-pO²ˉ diagram. It was found that the E-pO²ˉ diagram is equivalent to log aM-log Po₂ diagram. Difficulty was emphasized in the use of E-pO²ˉ diagram for reducing atmospheres. On the other hand, the proposed log aC-log Po₂ diagram shows the stability of alkali carbonates by any two of the parameters aC, Po₂, Pco, Pco₂, and aM. It was shown that the EMF of the carbonate electrochemical cells are obtained from the pfoposed diagram.
