Abstract
The heat capacity of titanium and zirconium was measured in the temperature range from approximately 1,300 K to 1,800 K . The measurement technique is based on the modulated power method originally proposed by Fecht and Johnson. The heat capacity of a sample can be derived from the sample’s temperature response to the modulated electromagnetic heating power if the sample’s total hemispherical emissivity is known. The experiments were performed using an electromagnetic levitator. The solid titanium and zirconium samples were suspended in the center of an induction coil with a very small diameter (0.15 mm) Pt (87 %)-Rh (13 %) wire. The heat capacity measurements of titanium and zirconium are presented, and the uncertainty is estimated to be ±3 %.
