Clay minerals consist of crystals in which atoms of silicon, oxygen and a number of metals, such as aluminum, iron and various rarer and less frequent ones, are arranged in a three - dimensional lattice.
Unlike water or regular ice, in superionic ice the water molecules dissociate into charged atoms called ions, with the oxygen ions locked in a solid lattice, while the hydrogen ions move like the molecules in a liquid.
The difference is that high pressure destructures the crystal lattice characteristic of quartz and compresses the silicon and oxygen atoms into an amorphous system.
Inside the AlloSphere, researchers such as Van de Walle use a joystick to maneuver through three - dimensional constellations of the oxygen, hydrogen and zinc atoms (linked by a complex lattice of chemical bonds) that make up these conductors.
Under similar pressures but higher temperatures, it has been suggested that ice X could possibly transform into a phase of ice that can conduct electricity as hydrogen atoms move freely around the oxygen lattice.
They took a common defect called a neutral oxygen vacancy — a place where an oxygen atom should appear in the lattice but instead two electrons are trapped.
A neutral oxygen vacancy, a place where an oxygen atom should appear in the lattice but is instead replaced by two electrons, is represented by the yellow shape, which depicts the charge density of those electrons.
In this diagram, the atomic lattice of a crystal of barium oxide is depicted, with atoms of oxygen and barium represented by red and gray spheres.
