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.
