Sh.G.Mammadov, I.B.Bakhtiyarli, A.N. Mammadov, V.S.Mammadov

 

For the first time by means of calculation methods there have been determined and tabulated standard entropies (), entropies (D), enthalpy (D) and free energy formations (D) of  quaternary compounds – Pb2SnSb2S6,  PbSnSb4S8 and also of ternary compounds – PbSb2S4, Pb5Sb4S11,  PbSnS2, SnSb2S4, Sn2Sb2S5, Sn2Sb6S11, formed in the boundary systems.

 

Keywords : pseudoternary system, thermodynamic functions, ternary and quaternary compounds, enthalpy, entropy
