Supercooling

Supercooling is the process of lowering the temperature of a liquid or a gas below its freezing point, without it becoming a solid. A liquid below its standard freezing point will crystallize in the presence of a seed crystal or nucleus around which a crystal structure can form. However, lacking any such nucleus, the liquid phase can be maintained all the way down to the temperature at which crystal homogeneous nucleation occurs.

Supercooling is the process of lowering the temperature of a liquid or a gas below its freezing point, without it becoming a solid.

A liquid below its standard freezing point will crystallize in the presence of a seed crystal or nucleus around which a crystal structure can form.

However, lacking any such nucleus, the liquid phase can be maintained all the way down to the temperature at which crystal homogeneous nucleation occurs.

Phase transitions. When the temperature is raised, the solid (crystal) melts, transforming into a liquid (white arrow) at exactly the melting point, TM.

When the liquid is cooled below TM (black arrow 1), solidification is possible but does not necessarily occur. In the striped area, a pure liquid (with no crystalline impurities) will not solidify.

If the liquid is cooled further, it will solidify (black arrow 2)
