Knudsen effusion mass spectrometry (KEMS) was used for direct determination of lead oxide activity as a function of temperature in various regions of the PbOΓZrO 2 ΓTiO 2 system. From the results, the enthalpy, Gibbs free energy and entropy of formation of PbTiO 3 (PT), PbZrO 3 (PZ) and Pb(Zr,Ti)O 3
