Last month the 10th edition of the famous international conference of Molten slags, fluxes and salts took place in Seattle, Washington, USA. This conference is organized every 4 years by TMS. It is a leading conference for sharing process and mechanistic knowledge in high-temperature processing. This time the focus lay in the field of extractive metallurgy and development of novel materials.
Surprisingly, a lot of presentations were focused on rare earth elements. Investigations varied from recycling possibilities, to thermodynamic studies and molten salt researches. It s very obvious that Rare Earth researches are finding their way into the spotlights and are definitely becoming a force to be reckoned with.
Some examples from presentations are:
- Electrochemical Recycling of Batteries using Molten oxides and Salts (Zhang Z. et al., Peking University)
- In situ observation of Rare earth containing precipitated phase crystallization and solidification of CaO-SiO2-Nd2O3 and CaO-SiO2-Nd2O3-P2O5 Melts (Le T.H., KULeuven)
- Techniques for measuring solubility and electrical conductivity in molten salts (Su S., Boston University)
- Surface properties of molten fluoride-based salts (T. Villalon, Boston University)
