Scientists got diamond's melting point wrong by more than 1,000 degrees, crushing new laser experiment reveals
Scientists blasted diamonds with lasers to get the best measurement of the mineral's melting point yet. The new, more accurate numbers could help improve fusion experiments and studies of giant planets.
Scientists have discovered that previous measurements of diamond's melting point were significantly inaccurate, off by more than 1,300 degrees Fahrenheit (700 degrees Celsius). This finding comes from new experiments that used a powerful laser to melt tiny plates of synthetic diamond, revealing the true melting temperature. The research, published in the journal Nature Physics, sheds light on the extreme conditions required for diamond to melt, providing valuable insights for nuclear fusion and understanding the composition of ice giant planets like Uranus and Neptune.
