When Pressure Builds Too Fast, Ice Gets Stuck in ‘Glassy’ Form

Amorphous Ice is an Experimental Side Effect of an Interrupted Crystal Transition

At high pressures and low temperature, water can form amorphous ice – a non-crystallized ‘glass-like’ solid that researchers had thought was related to supercooled water. New research, however, shows that amorphous ice occurs when ice gets stuck in an intermediate form in between two crystal structures.
