Abstract
The application of reaction calorimetry to metallic systems is examined. Different commonly used procedures and their respective fields of application are described: (a) direct and indirect drop method with flow calorimeters, (b) solid-solid reaction calorimetry (Kleppa's and Gachon's methods), (c) dissolution calorimetry in metallic baths, and (d) precipitation calorimetry. Some examples of results on binary and ternary alloys are given as illustrations: (a) the determination of the enthalpies of formation of metallic melts with respect to concentration and temperature, (b) the measurements of the enthalpy of formation of solid compounds, and (c) the determination of phase boundaries from isothermal reaction calorimetry.
