Diamond stays diamond even at extreme pressure
Scientists have discovered that diamonds maintain their crystal structure even under extreme pressures, up to 1 terapascal, before melting into a metallic liquid. This finding challenges previous assumptions about diamonds shifting into different crystal structures under such conditions. By crushing diamond samples with shock waves, researchers observed that the melting point of diamond dropped slightly as pressure increased. This data is crucial for understanding the interiors of giant planets, which experience immense pressures, and can also help refine nuclear fusion setups that utilize diamond components.
Key Points
- Diamonds maintain their crystal structure under extreme pressures, up to 1 terapascal, before melting.
- The melting point of diamond was observed to drop slightly as pressure increased.
- This research challenges previous theories about diamonds transforming into different crystal structures under high pressure.
- The data is valuable for understanding the interiors of giant planets and refining nuclear fusion setups.
Exam Facts
- Diamonds were subjected to shock waves reaching 1 terapascal.
- This pressure is approximately 10-million-times the atmospheric pressure.
- The diamonds melted into a metallic liquid at extreme pressures.
