New Superionic Ice Type Discovered Under Extreme Temperature and Pressure
Researchers in France have discovered a new type of superionic ice at 2,357 degrees Celsius by applying extreme conditions in a laboratory environment.
Scientists in France have revealed a previously unknown form of water thanks to intense pressure and temperature applied in a laboratory setting. The research showed that water acquires a distinct crystal structure at high temperatures.
Experiment in Laboratory Environment
Researchers led by physicist Alexis Forestier at the French Alternative Energies and Atomic Energy Commission examined in detail the behavior of water under extreme pressure and temperature in a laboratory setting.
Water, which is normally expected to transition to the gas phase or dissociate into its atoms at high temperatures, took on a completely different physical structure due to the intense pressure applied.
Diamond Anvil and Laser Technique
To create these unusual conditions, scientists used diamond anvils and advanced laser heating techniques.
Through these methods, water samples were subjected to exactly 2.3 million atmospheres of pressure and a temperature of 2,630 Kelvin.
Superionic Property and Structure
As a result of synchrotron X-ray analyses, it was determined that water transitioned into a crystal structure exhibiting superionic properties, referred to as hexagonal close-packed.
Superionic ice stands out as an exotic form of matter that can be defined as neither entirely solid nor entirely liquid.
Behavior of Atoms
In this special structure, oxygen atoms remain fixed within the crystal lattice while hydrogen nuclei move freely in a liquid-like manner.
It was determined that superionic ice, previously observed in a face-centered cubic structure, transforms into the hcp structure as pressure and temperature increase.
Secrets of Planets
Researchers state that this newly discovered crystal structure can make significant contributions to understanding the internal structure of ice giant planets such as Uranus and Neptune.
The electrical conductivity and mechanical properties of superionic ice deep within planets could shed light on the formation of the magnetic fields of these celestial bodies.
