Several simulation studies indicate that solid Ice-X at pressure >50 GPa, as the temperature is increased to 1,500–2,000 K, will dissociate into a superionic (SI) phase 1,2,3,4.In this phase ...

The phase diagram shows the state of water (H2O) under very high pressure (X-axis) and temperature conditions (Y-axis). These conditions apply in the interior of the ice planets Uranus and Neptune ...

This diagram, which plots temperature on one axis and pressure on the other, reveals the most stable phase of water at a given pressure-temperature condition. “These simulations are usually very ...

An example of a discontinuous phase transition is when liquid water reaches 100ºC and boils into a gas at normal atmospheric pressure. However, as pressure increases, ... The resulting ...

Water, a compound that is ubiquitous in our solar system and necessary for life, exhibits an exceptionally complex pressure-temperature phase diagram with 18 crystalline ice phases already identified.
