The present investigation has studied the step character of thermal decomposition of a natural antlerite employing the Fourier-transform IR spectroscopy; and new data on standardenthalpyofformation of antlerite by the method of
the standardenthalpyofformation of YbSn 3 using the dynamic differential calorimetry method. Colinet et al. [ 9 ] calculated by a semi-empirical model the enthalpies of formation of YbSn 3 [ 10 ] determined the enthalpies of formation for two
