A new form of ice has been discovered by scientists, expanding the world of water. When a drop of water was squeezed between two diamonds at high pressures, it solidified into a new crystalline phase at room temperature.
This new structure, called ice XXI, was discovered by researchers at the Korea Research Institute of Standards and Science (KRISS) and scientists at the European XFEL and DESY in Germany. It is the twenty-first form of ice ever identified.
Each form of ice emerges under unique combinations of temperature and pressure. Ice XXI now joins the expanding family of ice structures, showing that water's solid state is far more diverse.
Water's solid state is far more diverse than anything found in a freezer.
