摘要: Abstract Dynamic differential calorimetry has been employed to evaluate the heats of formation, and entropies fusion REPb3 compounds, where RE=La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm Yb. The results obtained have estimated be correct within ±5–6‰ general trend is a decrease in heat formation from La Tm, which correlated with magnitude lanthanide contraction these compounds.
