Supercomputer simulations by two Sandia researchers have significantly altered the theoretical diagram universally used by scientists to understand the characteristics of water at extreme temperatures and pressures.
The new computational model also expands the known range of water?s electrical conductivity.
The Sandia theoretical work showed that phase boundaries for ?metallic water? ? water with its electrons able to migrate like a metal?s ? should be lowered from 7,000 to 4,000 kelvin and from 250 to 100 gigapascals.
(A phase boundary describes conditions at which materials change state ? think water changing to steam or ice, or in the present instance, water ? in its pure state an electrical insulator ? becoming a conductor.)
