Abstract

Density of liquid titanium was measured free from any contamination over wide temperature range of 1640 and 2090 [K] including the undercooling condition by electrostatic levitator (ESL). When the diameter of upper electrode of ESL was modified to be smaller than that of lower one, it was decreased the uncertainty contribution of the droplet volume estimated from its image with respect to the density measurement by 30% through the suppression of the horizontal movement of the levitated droplet. The expanded uncertainties of the measurement plot were less than only ±1.4% when the coverage factor k = 2 was selected. Furthermore, it was evaluated the expanded uncertainty in the temperature dependence of density for liquid titanium expressed by a primary approximation of the plots.
