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 ...

The phase diagram between lead and tin shows the eutectic invariant reaction between these two constituents. At the eutectic temperature of 183 C, three phases exist in equilibrium: (Pb) with the ...

When a cupric oxide compound is subjected to high pressure, its Cu–O–Cu bond angle widens, strengthening the magnetic interaction between the ions. Using this phenomenon, this research team ...

Scientists have relied on phase diagrams for years to determine the states of various substances under specific conditions.
