Under isothermal conditions, the determination of the amount of heat induced to flow by a change in pressure allows to determine the expansivity a. Using a Calvet calorimeter and the piezothermal method the expansivity of Hg+In alloys has been measured in the pressure range 1–3000 bars. Two liquid alloys ( xIn = 0.075 and xIn = 0.143 ) have been studied at 262.5 K and 264.4 K, respectively. From these measurements we have deduced the variation of the liquidus temperature against pressure on the one hand and the melting enthalpy of the stoichiometric compound ( Hg6In) on the other hand.
