Inorganic melts based on fluoride salts are extremely corrosive; investigation of their
properties meets with remarkable technical problems. We have succeeded in implementation
of modern techniques for research of microscopic properties through collaboration with
internationally accessible laboratories. Macroscopic properties, such as phase equilibria,
thermodynamic quantities, density, viscosity and interfacial and surface tension were
measured using commercially inaccessible equipment for research prepared and build in our
laboratories.
Highly time consuming experiments provide important data mainly for industrial
applications. However, conclusions based solely on these results on processes occurring in
molten systems lack direct prove, they need further support. It was achieved via
implementation of new techniques like Rapid Solidification Processing and diffraction
experiments using neutron and synchrotron radiation. This approach of the team and the
results obtained were honoured by the Slovak Academy of Sciences Award in 2008.
