Abstract:The temperature dependence of the dielectric permittivity and losses of biocompatible Ca10(PO4)6(OH)2 ceramics were studied in a temperature range from 20 to 500°C. An approach to the interpretation of anomalies (bending points) observed in the dielectric characteristics of the ceramic samples is proposed, which takes into account features of the crystal structure of calcium hydroxyapatite and the defects formed in the course of thermal treatments.
