Changing Cement into Metal

Currently an international material experts at the Argonne National Laboratory developed a method to alter cement into metal which can be used as an electrical conductor. The raw material used is aluminum cement is composed of calcium and aluminum oxide. Materials are baked at a temperature of 2,000 degrees Celsius to melt. So as not to come into contact with the casing, made ​​with the help of wind drift from the bottom.

Then the melted cement is cooled in order to become crystalline. This turned out to be a new material such as glass. Electrons contained in these materials can move quickly. "It's the same properties as the metal," said physicist from the Argonne National Laboratory U.S. Department of Energy, Chris Benmore.

The process of metal making from cement is done at various air conditions. The oxygen bonding greatly affects the quality of the resulting crystals, and the researchers looking for the best air composition to produce the desired material. The metal resulting is the future technology that can be applied to a variety of technologies.
Close-up visualizations of (A) the HOMO and (B) LUMO single-particle electron states in the 64CaO glass. Both states are spin-degenerate, and h1 labels the cavity (cage) occupied by LUMO. Yellow and magenta stand for different signs of the wave-function nodes. (C) Simulation box and the electron spin-density of the 64CaO glass with one oxygen subtracted at h2—that is, with two additional electrons. The two electrons have the same spin and they occupy separate cavities, h1 (boundary, also shown in B) and h2 (center, location of removed oxygen), which are separated by 12 Å from each other. (D) Cage structure around the spin-density of one electron cor- responding to the h2 cavity (close-up from C). Al, gray; Ca, green; O, red. (Picture from: http://phys.org/)
The research team utilizing these new metal materials for thin film resistors that are used in flat-screen computer panel. And the corrosion which has been the enemy of metal, certainly will not be found on this new material. While its hardness level is higher than the crystalline material mostly. This material is also not affected by the magnetic field so that the electrons do not run out of energy when running in it.

The new metal is also malleable such as the cement properties. Discovery of the superior material done by the researchers team from Japan, Finland, Germany, and the United States. The results are published in the journal "Proceedings of the National Academy of Sciences" on May 27, 2012. *** [EKA | FROM VARIOUS SOURCES | PHYSORG | EPOCH TIMES | ANTON WILLIAM | KORAN TEMPO 4244]
