Ceramics based on biogenic hydroxyapatite have been produced via a microwave sintering at 1000 °C for 5, 10, 15, 20 and 30 min. It was shown that all of the ceramics studied exhibit volumetric shrinkage (2.3–4.6 %), which increases with increasing sintering time at maximum temperature. It was established that the total porosity did not depend on sintering time at 1000 °C and was equal to 38–40 %. Moreover, in all of the materials an open porosity dominated. The ultimate compression strength was in the range 35–40 MPa
