Description

Full text: A flow-through hydrothermal cell for the in-situ neutron diffraction study of hydrothermal crystallisation and phase transitions has been developed. It can be used for kinetic studies on materials that exhibit structural transformations under hydrothermal conditions. New fundamental knowledge on the mechanisms of phase transitions can thus be determined. It is specifically designed for the use on the Medium Resolution Powder Diffractometer at ANSTO, Lucas Heights, Sydney. But it is planned to adapt the design for the new High intensity powder diffractometer (Wombat) at the new Australian reactor Opal. The equipment has been initially created for the low temperature transformation study of Fe-Ni sulfide minerals. The design and use of the flow-through hydrothermal cell from 25 to 120degC are described. The first results of a successful transformation of pentlandite to violarite under mild conditions (pH 4) at 120degC and 3 bars using in-situ neutron diffraction measurements are presented.
