The authors further explain that the hexagonal diamond’s excellent thermal stability and ultra-high hardness suggest its great potential for industrial applications. They also noted that their findings provide valuable insights into the graphite-to-diamond conversion under elevated pressure and temperature, opening up opportunities for the fabrication and use of this unique material.
US researchers previously created hexagonal diamonds
The is not the first time the diamond has been developed in the lab. In 2021, a group of US researchers reported creating hexagonal diamonds large enough to measure their stiffness using sound waves.
