摘要

本文提出了一种比较简单的方法，利用标准设备通过差示扫描量热法估算熔体的混合焓。用这种方法测定了 CsX-PbX2 （X = Cl、Br）熔体的混合焓。在 CsCl-PbCl2 体系中测得的混合焓值与通过独立测量获得的值十分吻合。对于 CsBr-PbBr2 体系，混合焓是首次测量。两个研究体系的混合焓值相似。

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–PbX₂ (X = Cl, Br) melts are determined by this method. The measured values of mixing enthalpy in the CsCl–PbCl₂ system are in good agreement with those obtained by means of independent measurements. For the CsBr–PbBr₂ system, the enthalpy of mixing was measured for the first time. The similar values of mixing enthalpy were found for both studied systems.
