Hot ice is almost the surface of the Sun.

Super ion ice exists at the same time in liquid and solid form, forming at 4,725 degrees Celsius, close to the surface temperature of the Sun.

American scientists have successfully created super ion tape for the first time in the laboratory. The findings were published in February in the journal Nature Physics, according to Live Science.

Researchers have long argued that super ion ice, the high-pressure form of ice, exists in the crust of Uranus and Neptune, but that is only a theory."Our work provides empirical evidence for super-ionic ice and shows predictions not only based on simulations but actually reflecting the special state of water in extreme conditions , " Marius Millot, home Physics at Lawrence Livermore National Laboratory, said. Millot is the lead author of a study describing experiments that create super-ionic ice.

Researchers first predicted the existence of exotic water states both in liquid and solid form 30 years ago. Super ion ice is also denser than regular ice because it only forms under extreme temperatures and pressures like inside giant planets. In the super-ion state, hydrogen and oxygen in the water molecule show abnormalities. Hydrogen ions shift like liquids, inside solid lattices made of oxygen.

The process of creating super ion tapes is very complicated . First, the team compresses water into super-strong ice crystals, which are different from regular ice cubes. To do that, they use a diamond tip to create a pressure of 2.5 gigapascal, about 25,000 times the air pressure on Earth. Next, the researchers heated and compressed the anesthetic more strongly under the action of a laser. Each ice crystal structure is projected 6 lasers at a pressure 100 times higher.

As soon as the super ion band formed, the team quickly analyzed its optical and thermodynamic properties. They only had 10-20 nanoseconds to do the work before the pressure wave released the compressive force to melt the ice. The team found that the ice melted at 4,725 degrees Celsius and 200 gigapascal pressure. This pressure level is about two million times the atmospheric pressure on Earth.

"It's unbelievable that frozen ice exists at thousands of degrees Celsius inside the planets, but that's what the experiment shows," said Raymond Jeanloz, planetary physicist at the University of California. , Berkeley, co-author of research and sharing.

New discoveries may reveal conditions inside and. Planetary scientists speculate that water makes up 65% of the core mass of these planets, along with ammonia and methane.
