Abstract
- Thermophysical properties of liquid gadolinium were measured using non-contact diagnostic techniques with an electrostatic levitator. Over the 1585 K to 1920 K temperature range, the density can be expressed as ρ( T) = 7.41 × 10<superscript>3</superscript> − 0.46 ( T − T<subscript>m</subscript>) (kg · m<superscript>−3</superscript>) where T<subscript>m</subscript> = 1585 K, yielding a volume expansion coefficient of 6.2 × 10<superscript>−5</superscript> K<superscript>−1</superscript>. In addition, the surface tension data can be fitted as γ( T) = 8.22 × 10<superscript>2</superscript> − 0.097( T − T<subscript>m</subscript>)(10<superscript>−3</superscript> N · m<superscript>−1</superscript>) over the 1613 K to 1803 K span and the viscosity as η( T) = 1.7exp[1.4 × 10<superscript>4</superscript>/( RT)](10<superscript>−3</superscript> Pa · s) over the same temperature range.
