In today's episode, we're diving deep into the mysterious world of ice structures with Dr. Salamat. By utilizing advanced techniques like X-ray diffraction and Raman spectroscopy, his research provides novel insights into the transitions and behavior of ice under extreme conditions.

Methods and Techniques:

The study combined the use of X-ray diffraction and Raman spectroscopy. Grain normalizing heat treatment was achieved via direct laser heating, ensuring precise results.

Transition from Ice-VII to Ice-VIIₜ:

At pressures around 5.1 ± 0.5 GPa, a transition was observed from cubic ice-VII to tetragonal symmetry, denoted as ice-VIIₜ.

H-Bond Symmetrization Transition:

A significant event in the H2O structure is the H-bond symmetrization transition. This occurs at a pressure of about 30.9 ± 3 GPa.
