Making diamonds in a couple of minutes at room temperature has become a reality
Researchers have developed a new method for producing diamonds that allows two rare types of ultra-strong material to be created in minutes at room temperature.
For the formation of this mineral in nature, it is required that coal has been in the earth’s crust for millions of years at a depth of about 150 km, where enormous pressure and temperature will change its structure. Despite the existence of various technologies for the production of artificial diamonds, they usually mimic the necessary conditions on the surface and take a lot of time.

An international team of scientists, led by a team from the Australian National University, unexpectedly discovered that the same result could be achieved much faster and under normal temperature conditions. The essence of their method lies in the unusual way of applying high pressure, which more closely resembles the process of twisting or sliding.
Under such conditions, channels of ultra-strong crystal structures are formed from carbon atoms. The outer layer consists of lonsdaleite and the inner vein is made of ordinary diamonds.
In the future, the team will work on improving the new method in order to establish the production of large quantities of material for the needs of mining enterprises.
In addition to improving production technology, scientists are also inventing new types of ultra-strong materials with unique properties. So the researchers created rhenium nitride pernitride, which has a high electrical conductivity, like a metal, but is superhard, like a diamond.
