Abstract
The possibility of using quantitative differential thermal analysis to investigate phase transformations is examined. The temperature, enthalpy, and entropy of polymorphic transformations in LaGe1.8 and SmSi2 are determined: Ttr = 724 K, ΔtrH = 1635 ± 79 J · mole−1, ΔtrS = 2.3 ± 0.1 J · mole−1 · K−1 (LaGe1.8); Ttr = 658 K, ΔtrH = 1384 ± 69 J · mole−1, ΔtrS = 2.1 ± 0.1 J · mole−1 · K−1 (SmSi2).
