Sound velocity measurements of molten germanium

The temperature dependence of the sound velocity of molten germanium was measured up to 1200° C using a newly developed high-temperature ultrasonic measurement system. The system is based on the phase-comparison method and provides highly precise sound-velocity measurement. The temperature dependenc...

Summary:The temperature dependence of the sound velocity of molten germanium was measured up to 1200° C using a newly developed high-temperature ultrasonic measurement system. The system is based on the phase-comparison method and provides highly precise sound-velocity measurement. The temperature dependence of sound velocity of molten germanium showed softening near the melting temperature during both heating and cooling processes. This could be attributed to microscopic structural changes in the liquid.
