Under the micro-gravity environment, pure and high performance materials expected to be manufactured. It is possible to establish under-cooled condition for high temperature melted material levitated in space. The pure and high performance material is expected to be manufactured from the under-cooled condition. The purpose of the present study is to establish the technology of the high power ultrasonic wave system to levitate and control the high temperature melted material in space under the micro-gravity environment. From the results of the present study, it is confirmed that the simulated high temperature melted can be hold in a certain position in space by the ultrasonic standing wave. It is also clarified that the physical properties such as surface tension and viscosity can be measured with the present high power ultrasonic wave system. Furthermore, it is clarified that the temperature transient of the malted material can be established from above the melting temperature to below the melting temperature.

在微重力环境下，有望制造出纯净、高性能的材料。可以为悬浮在太空中的高温熔化材料建立欠冷条件。纯净且高性能的材料有望在过冷条件下制造。本研究的目的是建立高功率超声波系统在微重力环境下悬浮并控制太空高温熔融材料的技术。从目前的研究结果来看，证实了超声波驻波可以将模拟的高温熔化物保持在空间的某个位置。还阐明了可以用现有的高功率超声波系统来测量表面张力和粘度等物理性质。此外，还表明麦芽材料的温度瞬态可以从高于熔化温度到低于熔化温度建立。
