Abstract
The heat content of PuC above 298°K was measured with an isothermal drop calorimeter. No discontinuities were observed in the heat‐content‐vs‐temperature curve, which is described by the equation H T − H 298 =−5035+13.08T+5.718×10 −4 T 2 +3.232×10 5 T −1 . The equation for the heat capacity C P =13.08+11.44×10 −4 T−3.232×10 5 T −2 was derived from the calculated enthalpy equation. Values of the change in enthalpy,heat capacity, and entropy increments are given up to the melting point of PuC. Corrections of the enthalpy data for the self‐heating of plutonium and the defect structure of PuC are described.Keywords
