Abstract : Completely densified hydroxyapatite ceramics were successfully sintered in a 500 W microwave oven within 5 - 10 min at sintering temperature of 1100 - 1300 deg C. Compared with the hydroxyapatite ceramics sintered by the conventional method, the microwave sintered hydroxyapatite ceramics have the following characteristics: denser microstructure and finer grain size, as well as the improved mechanical strength, and the process consumes a small fraction of the energy and time of conventional sintering.
