At 1000 °C, the following assemblages are stable: MoS2 + ReS2 + S2(v); MoS2 + ReS2 + (Re,Mo)ss + v; MoS2 + Mo2S3 + (Re,Mo)ss + v; Mo2S3 + χ + (Re, Mo)ss + v, Mo2S3 + χ + (Mo, Re)ss + v. Experiments aimed at the determination of the MoS2-ReS2 solid state solubility reveal an asymmetrical behaviour: molybdenite dissolves 2.7(9) wt% Re at 1000 °C, 2.6(4) wt% Re at 800 °C, and 2.2(6) wt% Re at 400 °C, whereas ReS2 shows negligible Mo contents at all temperatures. The experimental solubility of ReS2 in MoS2 far exceeds Re contents in natural molybdenite, for which literature reports hundreds to thousands ppm.
