Thermophysical property data of basic fluid and high temperature melts have released.

-Thermophysical property data (density, surface tension, viscosity) of high temperature melts have released-

Release date: 2010/4/13

Summary of recorded data

Thermophysical property data of high temperature melts of pure metals have been recorded and released in cooperation with Takehiko Ishikawa, an associate professor at Japan Aerospace Exploration Agency (JAXA). Density, surface tension and viscosity of 22 materials listed below were recorded. These properties have been measured by the electrostatic levitation method. And valuable data of melts such as tungsten has a high melting point exceeding 3,000 degrees celsius have also been recorded.

List of recorded materials

Tungsten, Titanium, Zirconium, Niobium, Vanadium, Cobalt, Nickel, Yttrium, Molybdenum, Ruthenium, Rhodium, Palladium, Hafnium, Tantalum, Rhenium, Osmium, Iridium, Platinum, Lanthanum, Praseodymium, Neodymium, Cerium

Measurement method

Electrostatic levitation (ESL) is the method can measure various properties of molten metal without touching. Containerless float methods, including ESL, can avoid sample contamination because it has no reaction between container and sample. It can also produce supercooled state for solidifying for long periods of time. Therefore it is probably suitable for study on supercooled liquid. To measure density by ESL, calculate volume from camera image and mass divided by volume because its sample shape in suspension is nearly a sphere. Surface tension and viscosity are obtained from attenuance of frequency or vibration from vibrating a few drops of high temperature melt. (See reference 1 for details.)
