Gold in its purest form is a shiny metal, slightly reddish yellow, dense, soft, malleable and ductile. The melting point of gold is 1064.18 degrees Celsius. For practical use, gold is generally alloyed with base metals for use in jewelry, which modifies its hardness and ductility, melting point, color, and other properties.
A new way to melt gold was detected when Knoop 's researcher Ludvig examined a gold fragment under an electron microscope. Knoop noted that at the highest magnification, with an increased electric field, the atoms of gold changed.
Studying more closely the recordings made under the microscope, Knoop observed that the superficial layers of gold had melted at room temperature. This phenomenon has not been observed before.
This led Knoop to state in a research note: "I was really surprised by this discovery.This is an extraordinary phenomenon, which gives us new fundamental knowledge on the subject. 39; gold. "

The process was undertaken by exposing the atoms of a gold cone to a powerful electric field. The field excites the gold atoms, breaks their connections and causes the melting of the superficial layers. What happened was that the electric field made the atoms of gold lose their orderly structure and released almost all their connections.
What was of interest was other tests, it was also possible to change the gold between a solid structure and a molten structure.
On the basis of a set of theoretical calculations of the researchers, it is now possible to melt gold at room temperature based on a process called a small phase transition. This should be tested on a larger scale. Anyway, this knowledge could open new ways to the science of materials.
The research was published in the journal Physical examination equipment, with the research paper titled "Switching order reversible order and controlled by electric field of the surface of a metal tip".
