Mixing Enthalpy Estimation for CsX–PbX2 Melts (X = Cl, Br) by Differential Scanning Calorimetry

A comparatively simple method for estimating the mixing enthalpy of melts by differential scanning calorimetry using standard equipment is proposed. The enthalpies of mixing of CsX–PbX 2 (X = Cl, Br) melts are determined by this method. The measured values of mixing enthalpy in the CsCl–PbCl 2 syste...

Description
Summary:A comparatively simple method for estimating the mixing enthalpy of melts by differential scanning calorimetry using standard equipment is proposed. The enthalpies of mixing of CsX–PbX 2 (X = Cl, Br) melts are determined by this method. The measured values of mixing enthalpy in the CsCl–PbCl 2 system are in good agreement with those obtained by means of independent measurements. For the CsBr–PbBr 2 system, the enthalpy of mixing was measured for the first time. The similar values of mixing enthalpy were found for both studied systems.
