摘要
The authors use intense laser pulses to compress solid tantalum to pressures in excess of 20 million atmospheres. By combing their experimental measurements with existing high-pressure, high-temperature data on Ta, they can create an experimentally bounded high-temperature equation of state that is valid up to multiterapascal pressures and thousands of degrees kelvin. The equation of state may serve as a useful pressure standard at the extreme compressions and elevated temperatures now achievable in state-of-the-art static compression experiments. This work also provides a clear road map for building an accurate high-temperature equation of state catalogue of materials at extreme conditions.
