Description

Attempts have been made here to prepare phase pure greigite (Fe3S4) and polydymite (Ni3S4), by using thioacetamide as the sulphurising agent which is described in literature. This route proved not to be very efficient. 

 A new hydrothermal aqueous co-precipitation route was tested using DL-penicillamine as the sulphurising agent. By using the metal acetates and penicillamine as reactants it was possible to prepare both phase pure greigite (Fe3S4) and polydymite (Ni3S4).
