Diamond is known as the material the most solid on earth. However, it can be cut or shattered due to its atomic structure. For years, researchers have been studying the feasibility of synthesizing a diamond not presenting these flaws. Thanks to the advancement of research in atomic science, they are on the verge of achieving their goal.
A team of researchers from different countries including America, China and Germany have implemented a new method to create a less brittle diamond. This new technique gave birth to a paracrystalline diamond that meets various needs. Note that this material can be used in different fields of science and technology.
The team were able to create this material using carbon atoms arranged in a hollow spherical shape called “Fullerenes” Where “Buckyballs”. The study, titled Synthesis of Paracrystalline Diamond, was published in the journal Nature.
Paracrystalline diamonds can be mined at room temperature
According to phys.org, scientists used the classic approach creation of the diamond to develop the crystalline diamond. The method involves subjecting the carbon-based material to an elevated temperature of between 1,652 and 2,372 ° F (900 and 1,300 ° C).
It should be lifted that the pressures exerted on the material can go from 27 to 30 gigapascals. This means that these are much lower than those used for the manufacture of commercial diamonds.
During processing, the buckyballs had to collapse to form transparent paracrystalline diamonds that can be mined at room temperature. The team then examined their finished product using a electronic microscope in order to define its structure.
The diamond consisted of messy sp 3 hybrid carbon
The team used the x-ray diffraction and atomic modeling to analyze their sample in depth. These processes led to the conclusion that paracrystalline diamonds consist of messy sp 3 hybrid carbon. This is the result that the researchers were waiting for in order to create a less fragile diamond.
They also noted that the diamond they created is not completely amorphous as a type of glass. This is contrary to the results obtained during another recent attempt to synthesize a less brittle diamond. In fact, this product is a type of medium order amorphous diamond paracrystal. As there is no plane of atoms, diamonds here cannot be cut like traditional diamonds.
