From the dissociation pressures of ferrous sulphide the chemical constant of sulphur vapour S2 was calculated. Using this Value the dissociation pressures of cuprous sulphide at several temperatures was theoretically calculated.
The comparison between these values and values which were obtained from Jellinek, Britzke and Sanos data concerning to the reduction equilibrium of cuprous sulphide by hydrogen was also made.
