Abstract

An electrostatic levitator was developed for the structural analysis of high-temperature and undercooled liquids by X-ray diffraction. The apparatus can be used to investigate the structure of metallic, semiconductor, and ceramic liquids. Samples of zirconium, silicon, and alumina in their liquid phases could be kept levitated for more than one hour with this apparatus. This was sufficiently long to perform a detailed analysis of the liquid structure by X-ray diffraction techniques., 資料番号: AA0063323003, レポート番号: JAXA-RR-06-015E

Abstract

X線・中性子散乱法と静電浮遊炉を組み合わせることにより、超高温や過冷却液体の構造を精密に測定することが可能である。本研究は、シリコンやジルコニウムなど高温金属液体の液体構造を測定するために、構造解析用の静電浮遊炉を新たに開発し、高輝度放射光および中性子線を用いた散乱実験を試みた。実験の結果、これらの液体の静的構造因子(過冷却液体状態を含む)を高精度に測定することができた。, The structure of undercooling liquid state is one of the important subjects of materials science. The levitation techniques are powerful tools for the investigation of undercooled liquids. In this research, we developed the electrostatic levitation furnace for the liquid structure analysis due to the neutron and x-ray diffraction methods. The apparatus was tested by using a synchrotron radiation facility, a laboratory X-ray source and a reactor. The structures of several kinds of materials were investigated and the liquid structures can be measured with high precision., 資料番号: AA0049301004, レポート番号: JAXA-RR-05-034E

Abstract

ElectroStatic Levitator (ESL) levitates a charged sample in a high vacuum using computer controlled electrostatic fields. It can levitate materials such as metals, semiconductors, and some insulators. Sample temperature can be varied over a wide range, and samples may be deeply undercooled. ESL allows us to carry out back-ground free measurements since it can hold the sample without a vessel in a high vacuum, and so ESL is suited to measure elastic- and inelastic X-ray scattering of high temperature and undercooled melts using synchrotron radiation factory., 資料番号: AA0063706011
