Development of Thermophysical property measurements system for high temperature oxide melts by a pressurized electorstatic levitator

本研究的目的是利用静电悬浮法建立高温氧化物熔体的热物性测量系统。已研制出一种可加压至10个大气压的静电悬浮器。然后，进行了悬浮和熔化氧化物样品的试验。由于样品周围的高压气体和氧化样品表面电荷的断裂导致的位置传感问题给稳定悬浮带来了困难。ZrO_2的热物理性质，本研究的最终目标尚未完成。我们将继续这项研究的目标。

The aim of this research is to establish a thermophysical property measurement sysytem for high temperature oxide melts using an electrostatic levitation method. An electrostatic levitator has been developed which can be pressurized up to 10 atomosphere. Then, trials were made to levitate and melt oxide samples with it. Several issues including position sensing problem due to the high pressure gas around the sample and the fractuation of surface charge on the oxide samples made the stable levitation difficult. Thermophysical properties of ZrO_2, the ficnal goal of this research has not been completed yet. We will continue this research to the goal.
