Single crystal structural studies of alkali carbonates Na2CO3, K2CO3 and NaKCO3 at high pressures and temperatures

This proposal aims to study the Na2CO3 - K2CO3 system from a structural point of view using single crystal diffraction at simultaneous high pressure and temperature in the range 0-15 GPa and 0-1200 K with resistive heated DACs. The experiments are aimed both at the structural determination of alkaline carbonates at variable pressures and temperatures, and at the determination of accurate thermal EoS for the different polymorphs.
