An elongate field of high-form pentlandite solid-solution, Fe 5.65 Ni 3.35 S 7.85 , β 2 (Ni 4± x S 3 ), occurs in the system Fe–Ni–S at 650°C. This solid solution coexists with monosulfide solid-solution, β 1 (Ni,Fe) 3± x S 2 and γ (Fe,Ni). Pentlandite with a composition Fe 5.60 Ni 3.40 S 7.82 first appears as a stable phase at 625°C owing to the phase transition of the most Fe-rich high-form pentlandite with the same composition. It grows as a limited solid-solution, from Fe 5.64 Ni 3.36 S 7… Expand
