The enthalpy increment of solid antimony has been measured by drop calorimetry from 486 to 858 K. The results can be represented by:{H-0(T) - H-0(298.15 K}/Jmol(-1) = 19.5569(T/K) + 6.14137 x 10(-3)(T/K)(2) - 1.83207 x 10(5)(T/K)(-1) - 5762.3In addition, an assessment of the low-temperature heat capacity data has been made, yielding S-0(298,15 K)=(45.42 +/- 0.45) J K-1 mol(-1). From the combined results, the thermodynamic properties of solid antimony have been calculated.
