Aerodynamic levitation technique for containerless high temperature studies on liquid and solid samples

TastyFloats

“…Winborne et al [55] achieved aerodynamic levitation of liquid metals using a nozzle-focused jet of air. His method, however, does not support low viscosity liquids (e.g., water).…”

Properties of high-temperature melts using levitation

“…The CNL method was first used in combination with EM heating of levitated aluminum and uranium liquid [20]. Later, Coutures et al [21] introduced CO 2 laser beam heating and reported numerous investigations of liquid oxides, including structural investigations by NMR and EXAFS [22][23][24].…”

Comparative Study on Structural Variations during Containerless Solidification Processes of Fe-B and Fe-C Eutectic Alloys

“…13) One such approach is conical nozzle levitation (CNL), in which a spherical sample is levitated by gas flow in a conical nozzle. 14) Because of its simplicity compared with another levitation technique, CNL is a versatile technique and can be readily combined with different kinds of experimental apparatus. Indeed, CNL is often used when performing x-ray diffraction experiments on high-temperature melts and solidification from the undercooled liquids.…”

“…Indeed, CNL is often used when performing x-ray diffraction experiments on high-temperature melts and solidification from the undercooled liquids. [13][14][15][16][17][18][19] While time-resolved x-ray diffraction (TRXRD) and imaging techniques for studying solidification of steels have been developed with utilizing high-flux x-rays from a synchrotron radiation source, 20,21) synchrotron TRXRD experiments combined with CNL have been also carried out by adopting a two-dimensional detector such as a charged coupled device (CCD) for investigations of structural variation during solidification from deeply undercooled melts. 18,19) In the present study, we conducted TRXRD experiments during containerless solidification of Fe-C and Fe-B binary alloys at the eutectic composition.…”
