Diamond is famously known as the hardest mineral on Earth. But researchers have been pursuing an unusual variant of it — known as hexagonal diamond — that might be even harder. After decades of claims ...

To synthesize the crystals, the team compressed highly ordered pyrolytic graphite to pressures as high as 20 gigapascals, roughly 200,000 times the atmospheric pressure at Earth’s surface.

Diamonds are famous for their strength, but scientists have long suspected that another form of diamond might be even harder. Evidence of this was gathered over the past sixty years in meteorite ...

3月5日，郑州大学金刚石材料与器件团队成功合成出纯相六方金刚石块材，并精确解析了其晶体结构，揭示了全新的相变机制。相关研究成果以“Bulk hexagonal diamond”为题发表在国际学术期刊《自然》（Nature）上。 郑州大学物理学院博士研究生来守龙、杨西贵教授 ...

IT之家 3 月 8 日消息，据郑州大学物理学院，近日，该院金刚石材料与器件团队成功合成出纯相六方金刚石块材，并精确解析了其晶体结构，揭示了全新的相变机制。相关研究成果以“Bulk hexagonal diamond”为题，于北京时间 2026 年 3 月 5 日在线发表在国际学术期刊 ...

Currently, diamond is regarded to be one of the hardest and most scratch-resistant natural materials in the world. Most diamonds found in nature and often used in jewelry display a cubic crystal ...

For the first time, researchers have hard evidence that human-made hexagonal diamonds are stiffer than cubic diamonds found in nature and often used in jewelry. Hexagonal diamonds have been found at ...
