Nanocrystalline iron sulphide (FeS) coated with polyvinyl alcohol, with particle size ranging from several to several tens of nanometres, has been prepared by the chemical precipitation synthesis method. The phase transition of FeS has been investigated by using in situ high-pressure diffraction with synchrotron radiation at pressures up to 42.5 GPa. Most of the diffraction lines are broadened and weakened. At the pressure of 11.8 GPa, a new phase transition was observed. However, only eleven x-ray reflections were recorded under high pressure; the crystal structure is unknown.
