概要

• 論文の詳細を見る

• A nano-polycrystalline diamond was synthesized from graphite by direct conversion under high pressure. The nano-polycrystalline diamond consists of nanosized diamond grains oriented in random directions and has higher toughness and more isotropic mechanical properties than the single-crystal diamond. We generated the pressure using a pair of anvils composed of nano-polycrystalline diamond particles. The highest generated pressure achieved was 210 GPa. The generated maximum pressure was almost the same as that achieved by the single-crystal diamond anvils.
