MERCURY Number 80 on the "periodic table" of elements Mercury or "quicksilver," is a shiny liquid metal that is a widespread environmental contaminant. The levels of mercury in our bodies today are much higher because of its greater use in recent times. Mercury is employed daily by medical and dental practices in thermometers, drugs and amalgam for fillings.
Redefining Metals for the 21st Century Department of Energy united to help develop a new building material. Liquidmetal Technologies It has long been thought that plastic and steel were the best materials to use in building large products that might be used for aerospace and space exploration applications.
These new "shapeless alloys" combine the strength of steel with the molding capability of plastic. Bill Johnson of Caltech, Pasadena, Calif. He eventually teamed up with Dr. Peker further helped Johnson develop the idea of creating thick liquid metals that form glass without the need for rapid cooling.
NASA and Liquidmetal Technologies cooperated on research using the microgravity conditions available flying on the space shuttle. Extensive experiments on liquid metals were conducted onboard the International Microgravity Laboratory flight in and again in on the Microgravity Science Laboratory mission.
Department of Energy to create new materials for aerospace. Liquidmetal engineers and Rawlings designers developed a baseball bat that offers superior durability while dramatically reducing the energy loss experienced with other materials upon impact with the ball.
Liquidmetal technology is currently exclusive to Rawlings for baseball and softball bats. Liquidmetal Technologies Johnson has continued this research on the ground using electrostatic levitation and laser heating. In this process small spheres are held up in a vacuum and melted by a laser beam.
Johnson and Peker were able to create a new form of mixed metals that went from a liquid to a solid at room temperature. The liquid included a mix of elements: Instead of having to quickly cool a liquid metal to become solid, it cooled and hardened itself at room temperature to avoid crystallization and become a glass.
They named this liquid metal "Vitreloy. Although this material had super strength, it lacked the attributes that make metals tough. Vitreloy, was more robust than window pane glass, but still cracked.
Liquidmetal is the only material that can fully exploit the energy that is released during a turn-without any losses whatsoever. At the same time, the special molecular structure guarantees fastest response and markedly improved ski rebound for optimum turn initiation.
Skis made of materials with conventional molecular structure lose too much power during turns as a result of heat and strong ski deformation.
Liquidmetal Technologies The successful method used to toughen Vitreloy and create Liquidmetal is the same method used to process plastics.
InJohnson and graduate student Paul Kim improved Vitreloy's toughness while giving it the flexibility to allow it to be made into many different shapes.
Now, the new line of Liquidmetal alloys is on the rise.Mercury was thought to be the key to the transformation of base metals into gold (the holy grail of alchemy), perhaps because the noblest and most precious of metals actually dissolves in the stuff.
The mercury-indium phase diagram has been investigated over the whole composition range from −78°C to the melting point of indium, using thermal analysis, X-ray and superconductivity techniques.
This is believed to be the first application of superconductivity measurements to phase diagram investigations.

This is believed to be the first application of superconductivity measurements to phase diagram investigations. Tin becomes liquid at ˚C (˚F); at the other end of the spectrum, tungsten has the highest melting point of any metal: 3,˚C (6,˚F). Somewhere in the middle is mercury, which stays in a liquid state until its temperature drops to °. Mercury is the only pure metal liquid at room temperature, as odd in its way as water. The eutectic alloy of % Na and % K melts at °C, so it also is a liquid at room temperature. The name hydrargyrum, "water silver," was given by Pliny from Greek roots for the common name, and is the source of its chemical symbol, Hg.
Presented herein are the results from the Task 1 nondestructive testing studies conducted under the a research program entitled, "Combatting Liquid Metal Attack of Aluminum Alloys by Mercury in Ethylene and Cryogenic Gas Plants".

Mercury exists in a number of different forms: elemental mercury. metallic mercury inorganic mercury compounds. organic mercury compounds. Elemental or metallic mercury is a shiny, silver-white metal and is liquid at room temperature. Liquid metal embrittlement is the decrease in ductility of a metal caused by contact with liquid metal.
The decrease in ductility can result in catastrophic brittle failure of a normally ductile material.
