AsianFin – A team of researchers from Jilin University's National Key Laboratory of High Pressure and Superhard Materials, along with the Comprehensive Extreme Conditions High Pressure Science Center led by Professors Liu Bingbing and Yao Mingguang, in collaboration with Professor Zhu Shengcai from Sun Yat-sen University, have made a significant breakthrough.
They published a paper titled "General Approach for Synthesizing Hexagonal Diamond by Heating Post-Graphite Phases" in Nature Materials.
The team discovered a new pathway for the formation of hexagonal diamonds from graphite under high temperature and pressure.
They have successfully synthesized high-quality hexagonal diamond blocks for the first time, which exhibit hardness superior to cubic diamond and excellent thermal stability.
This research not only provides an effective method for the artificial synthesis of pure hexagonal diamonds but also offers strong evidence of their independent existence.
The achievement introduces a new member with superior performance to the field of ultrahard materials and novel carbon materials, potentially breaking the limitations of cubic diamond applications.
Furthermore, the findings have significant implications for understanding the specific origins of diamonds in meteorites and major geological events.
