Notes:
Two-step sintering was performed to prepare hydroxyapatite (HAp) with a high densityand a fine microstructure utilizing hydrothermally synthesized nano powders. Its effectiveness wasdependent on starting chemicals for precursors of HAp, powder processing condition, initialtemperature in the two-step sintering, heating rate to the initial temperature, and holding time atfinal temperature. HAp powder, hydrothermally treated after aging of precipitate of Ca(OH)2 andH3PO4 for 48 h, led to HAp having a high phase stability at elevated temperatures, a high density,and a fine microstructure after two-step sintering with heating rate of 10°C/min to 1275°C
