Copy of: Search for density and diffusivity water-like anomalies in a ionic melt

Abstract: Many network-forming liquids exhibit water-like thermodynamic and kinetic anomalies, the most obvious of which concerns the presence of a regime of anomalous densities as well as an increase in molecular mobility with increasing density, witnessed by a diffusional anomaly which corresponds to a regime in which the diffusivity increases as a function of density, in stark contrast to the behaviour of simple liquids. Molten BeF2 represents a close structural and thermodynamic analogue to silica which because of the weaker Be¿F interaction, shows both melting (1076 K) and glass-transition (580 K) points at significantly lower temperature than silica making the regime where anomalous behaviour are predicted by simulations amenable to experiment. Here we wish to propose to conduct a diffraction and quasielastic scattering study aiming to confirm the simulation results.
