Heat capacity of liquid hafnium from the melting point to the boiling point at atmospheric pressure
Annotation
The temperature dependence of the heat capacity of highly pure hafnium (zirconium content of $0.14\%$ by mass) in the liquid state is measured from the melting point to $5000$ K. A sample in the form of a wedge made up by two thin strips of hafnium foil is heated by an electric current pulse. The temperature is measured by a high-speed pyrometer. The radiation from the space formed by foil strips is directed to the pyrometer via fiber-optical light guide. The specific heat capacity of liquid hafnium at atmospheric pressure from the melting point $(2504$ K$)$ to the boiling point $(4875$ K$)$ exhibits an increasing pattern similar to that of the previously investigated heat capacity of liquid zirconium.
