Heat Flow Calorimetry

The dependence of the phase transition behavior of indium and tin on pressure and heating rate has been investigated using heat flow calorimetry (HFC). The work has shown a significant influence of heating rate on the form of the melting curve, onset temperature for both indium and tin, as well as the enthalpy of fusion for indium. Based on the result for the dependence of onset temperature on pressure, the volume changes on fusion have been estimated using the Clausius–Clapeyron equation and compared with literature results.Key words: indium, tin, high pressure, heat flow calorimetry calibration, fusion temperature, enthalpy of fusion.
