Concerning the graphical representation of metallurgical equilibria contributing to the rationalization of metallurgical practice, a study on the dissociation reactions of metallic sulfides, for an example, was made. For the dissociation reactions of metallic sulfides the following relation is established in general : [numerical formula] where pS_2 is the dissociation pressure of metallic sulfide, T the absolute temperature and ΔH the change in heat content. And ΔH is approximately regarded as a constant so long as each substance in a reaction system has neither transformation point nor melting point, which is accompanied with considerable thermal change. In the light of these facts, a method was described by means of which the lines representing the effects of temperature on the changes in dissociation pressure of metallic sulfides were drawn on a diagram where (-log pS_2) and (10^4)/T were denoted on the ordinate and abscissa respectively.
