LOW DIMENSIONAL NETWORKS UNDER PRESSURE. IN-SITU DIFFRACTION MEASUREMENTS OF CARBONATE GLASSES.

DOI

Carbonate liquids are characterised by low temperature and low viscosity and play an important role in molten carbonate fuel cells, battery electrolytes and, surprisingly, in volcanic processes. Indeed they are important agents of element transfer in the deep Earth interior. Despite their unique role determined by structure-related properties little is known about the carbonate liquid structure. A recent study has shown that the liquid structure comprises chains of linked, triangular carbonate anions which form a low-dimensional network. This network is temperature dependent and chains decrease in length with temperature. The aim of this work is to determine what happens to the carbonate chains when pressure is applied. The experiment will comprise a set of diffraction measurements, combined computer simulation, and will to explore the high pressure behaviour of these exotic glasses.
