Thermophysical property measurements of molten nickel using an electrostatic levitation furnace

Thermophysical properties of liquid and supercooled nickel were measured using electrostatic levitation. Over the 14201850 K temperature range, the density can be expressed asp(T) =7.89 x 10(3)-0.65(T- T-m) (kg(.)m(-3)) with melting temperature T = 1728 K. The isobaric heat capacity was estimated as C (T) =36.2 + 1.9 x 10(-3)(T-T-m) (J(.)mol(-1.)K(-1)) over the 1420-1850 K interval by assuming a constant emissivity. The volume expansion coefficient was also calculated as 8.2 x 10(-5) K-1. In addition, the surface tension can be expressed as gamma(T) = 1739-2.2 x 10(-1)(T- T-m) (10(-3) N(.)m(-1)) and the viscosity as eta(T) =0.07 exp [6.7x 10(4)/(RT)](10(-3) Pa(.)s) over the 1553 to 1963 K temperature range.
