Abstract
The standard enthalpies of formation of LnMIIMnFeO5.5 manganitoferrites (Ln is a rare-earth element, and MII is an alkali-earth metal) were estimated by the developed method of calculation. Their standard entropies were calculated by the method of ionic increments, and their standard Gibbs energies of formation were determined by the Gibbs-Helmholtz equation.
