| Abstract: | The thermodynamic activity of sulfur in the β1-Ni3S2, β2-Ni4S3, γ-Ni6S5 and δ-NiS phases was determined as a function of composition over the temperature interval, 823 to 1023 K, using a gas equilibration technique. The data obtained in the present study as well as those reported in the literature are evaluated to yield thermodynamic equations of state for all the intermediate phases. Several forms of the Ni-S phase diagram are presented. The previously reported “Ni3S2” phase was found to consist of two phases designated as β1-Ni3S2 and β2-Ni4S3 in the present study. |
