China develops 'unbreakable' diamond with carbon nanotube reinforcement

Chinese scientists have developed a new type of diamond that is significantly tougher than traditional diamonds, overcoming their inherent brittleness. By incorporating multi-walled carbon nanotubes into an internal support structure, the material's toughness has been increased sixfold without compromising its hardness. This breakthrough, detailed in Nature Synthesis, results in a material even more resilient than the alloys used in armor-piercing ammunition. AI

    Tougher than armour, hard as diamond: China’s unbreakable crystal breakthrough

    Chinese scientists have created a diamond with no Achilles’ heel – one that cannot be broken, even by a hard knock with a hammer – according to a paper published in the peer-reviewed journal Nature Synthesis. While a diamond is the hardest natural material on Earth, it has a majo…
