Dynamic differential calorimetry of intermetallic compounds I. Heat of formation,heat and entropy of fusion of rare earth—tin compounds

Dynamic differential calorimetry has been employed to evaluate the heats of formation, heats and entropies of fusion of RESn₂ compounds, where rate earths (RE) La, Ce, Pr, Nd, Sm, Gd, Eu, Yb and Ca. The results obtained have been estimated to be correct to within ±5–6%. The agreement between these values and those obtained from other authors can be taken as an indication of the reliability of the method.
