The present disclosure describes a compression device, a compression process, a method of producing synthetic materials and a method of sample characterization. The present disclosure belongs to the fields of Physics, Chemistry and Engineering.
The study of materials under high pressures is of great scientific and technological interest. High pressures can be found inside planets and the study of these material's behavior is extensively carried out in the fields of chemistry and physics.
Several equipment to increase the pressure in a controlled way can be found in the state of the art, among them we can highlight the anvil cells, mainly the diamond anvil cells.
A diamond anvil cell comprises at least two diamonds (anvils) with a cavity between these anvils. By applying force, bringing the two diamonds together, the pressure inside this cavity is increased several times.
This diamond anvil cell is a high pressure cell used in a wide range of techniques for studying the properties of materials at high pressures, for example techniques using synchrotron light sources such as spectroscopy, x-ray diffraction and Raman spectroscopy.

In the document, they comment that it takes a force of 10,000 N to generate a pressure of just 100 gigapascal.
