Zhengzhou University Researchers Create Harder Lab-Made Hexagonal Diamond from Graphite
Researchers at Zhengzhou University have successfully created a pure hexagonal diamond that tests slightly harder than natural diamonds. This lab-made diamond, formed under extreme pressure and heat from graphite, resolves a long-standing debate about the existence of hexagonal diamonds. Using X-ray diffraction and Vickers hardness tests, the team confirmed the diamond's structure and thermal stability, suggesting potential applications in cutting, drilling, and electronics. Future research will focus on producing larger samples and comparing them with engineered diamonds.

Researchers at Zhengzhou University have created a pure hexagonal diamond that tests slightly harder than many natural diamonds, resolving a long-standing debate regarding this carbon structure. The diamond was formed from graphite under 20 gigapascals of pressure and temperatures between 1,300 and 1,900°C.
The resulting sample underwent X-ray diffraction, confirming its hexagonal structure, and Vickers hardness tests indicated it reached about 114 gigapascals under a 9.8-newton load. This diamond exhibits strong thermal stability, making it suitable for applications in cutting, drilling, and electronics. Future research will focus on producing larger samples and comparing them with engineered diamonds.
