Abstract A liquid metal solution calorimeter and its operation are described. The method of calculation is outlined and the sources of error are analyzed. In this calorimeter, heat effects upon dissolution of samples in liquid metals are measured; heats of solution are determined directly and heats of formation, energies of ordering, and the stored energy of cold work are found by a difference method. The calorimeter operates in the temperature range 240 to 450°C; samples are added from 0 or -195°C. Finally, highest accuracy, of the order of ±2 cal/g-atom, is attained with suitably chosen solute-solvent combinations giving very small total heat effects upon dissolution.
