Аннотация: The thermal expansion of the CaCu3Ti4O12 ceramics has been measured over a wide temperature range 120-1200 K. The high quality of the samples under study has been confirmed by good agreement of the results of measurements of the heat capacity in the range 2-300 K and in the vicinity of the phase transition of magnetic nature at 25 Показать полностьюK with the data for the single crystal. No anomalies in the thermal expansion that can be associated with the phase transition at 726-732 K assumed by other investigators have been found. The influence exerted on the thermal expansion by the heat treatment of the sample in a helium atmosphere and in air has been investigated.
