Pentlandite is the dominant Ni-hosting ore mineral in most magmatic sulfide deposits and has conventionally been interpreted as being entirely generated by solid-state exsolution from the high-temperature monosulfide solid solution (MSS) (Fe,Ni) 1–x S. This process gives rise to the development of loops of pentlandite surrounding pyrrhotite grains.

Pyrrhotite (obtained from Tongling City, Anhui Province, China) was fragmented in a jaw crusher and sieved into particles of 2.36–5.12 mm in size. Pyrrhotite particles were placed in a 10% (v/v) HCl solution for 2 h for the removal of oxides formed on the surface, and rinsed with deionized water until the pH of the rinse reached 7 ± 0.1.

The pyrrhotite material was handpicked from an 80 cm thick massive lense of sulphides in the open pit of the Akselberg deposit, and subsequently crushed using a jaw crusher with 3 mm discharge opening. To minimise the degree of oxidation of the particle surfaces, the crushed material were stored in a freezer until used in the experiments.
