Intrinsic or stoichiometric defects-they do not change the overall composition of the crystal- (Schottky and Frenkel defects, estimation of the number of defects based on the statistical thermodynamic). Extrinsic defects created when a foreign atom is inserted into the crystal lattice-hopping or vacancy mechanism (nonstoichiometric oxides, electronic defects). Ionic conductivity in solids. Demonstration of the lab exercise: “Determination of the ratio Mn3+/Mn4+ in manganites. Indirect determination of the sub-stoichiometry of oxygen”.
