Important properties of crystalline solids are due to deviations from the ideal crystal structure. Lattice defects can be divided into structural defects (grain boundaries, dislocations, impurities) and intrinsic defects. The present article deals mainly with the problems and possibilities for the determination of intrinsic disorder. This disorder, which varies reversibly with temperature, plays an important role in many solid‐state processes, such as diffusion, ionic conduction, and chemical reactions in the solid phase. After an introduction to the usual physical and chemical descriptions of the state of disorder, the principal methods of investigation are discussed. Special emphasis is placed on methods of determining disorder data from “anomalous” specific heats.
