Abstract
A flow-through hydrothermal cell for the in situ neutron diffraction study of crystallisation and phase transitions has been developed. It can be used for kinetic studies on materials that exhibit structural transformations under hydrothermal conditions. It is specifically designed for use on the medium-resolution powder diffractometer (MRPD) at ANSTO, Lucas Heights, Sydney. But it is planned to adapt the design for the Polaris beamline at ISIS and the new high-intensity powder diffractometer (Wombat) at the new Australian reactor Opal. The cell will operate in a flow-through mode over the temperature range from 25–300 1C and up to pressures of 100 bar. The first results of a successful transformation of pentlandite (Fe,Ni)9S8 to violarite (Fe,Ni)3S4 under mild conditions (pH4) at 120 1C and 3 bar using in situ neutron diffraction measurements are presented.
