Thermal property determination for phase change materials1

Abstract Phase change materials have important roles in a more energy-efficient world. However, the literature concerning their thermal properties is not always as accurate as it could be. Three important physical properties of phase change materials, as determined by differential scanning calorimetry, namely transition temperature (Ttrs), enthalpy of fusion (ΔfusH), and heat capacity (Cp(T)), are examined, and recommendations are made concerning accurate property determination.
