Abstract

"A static method was used to determine equilibrium sulfur pressure for molybdenum-sulfur mixtures at 1100°C.

The results obtained were:
(1) The molybdenum disulfide phase was stable in a sulfur pressure range of 1.023 x 10-5 to 6.026 x 10-1 atmospheres. A range of non-stoichiometry from MoS2.00 to MoS2.22 was determined under these conditions.
(2) The upper limit of sulfur content of molybdenum sesquisulfide (Mo2S3) is nearly stoichiometric.
(3) The extent of solid solution of sulfur in molybdenum is approximately 1.5 atomic % (0.5 wt %).
(4) Molybdenum sesqu-isulfide (Mo2S3) formed at high temperatures is stable at 600°C.

Integral free energies of formation of equilibrium mixtures of Mo and S from solid Mo and diatomic sulfur vapor were calculated"--Abstract, page iii.
