Observation of Rapid Solidification of Deeply Undercooled Si Melts Using Electrostatic Levitation

Autor: Paradis, Paul-Francois, Aoyama, Tomotsugu, Ishikawa, Takehiko, Yoda, Shinichi

Publikováno v: Materials Sciences and Engineering. A. :460-463

Pure Si samples with diameters of about 1.7 mm were undercooled down to 317 K while electrostatically levitated. The crystal growth velocities were measured as a function of undercooling and the appearance of the solid/liquid interface was observed b

An aerodynamic levitation system for drop tube and quenching experiments

Autor: Paradis, Paul-Francois, Arai, Yasutomo, Aoyama, Tomotsugu, Ishikawa, Takehiko, Yoda, Shinichi

Publikováno v: Review of Scientific Instruments. 74(2):1057-1063

This article describes an aerodynamic levitation system for the processing and study of undercooled insulator materials by drop tube and quenching experiments. Its operation principle relies on a convergent-divergent type aerodynamic levitator made o

Thermophysical properties of vanadium at high temperature measured with an electrostatic levitation furnace

Autor: Paradis, Paul-Francois, Ishikawa, Takehiko, Aoyama, Tomotsugu, Yoda, Shinichi

Publikováno v: The Journal of Chemical Thermodynamics. 34:1929-1942

Four thermophysical properties of both solid and liquid vanadium: the density, thermal expansion coefficient, molar heat capacity at constant pressure, and hemispherical total emissivity, are reported. These thermophysical properties were measured ov
