A new technique for preparation of powders in multi-component system such as hydroxyapatite under hydrothermal conditions was designed. In this technique, Ca(NO3)2 and (NH4)2HPO4 solutions separately heated to a desired reaction temperature in a multi-chamber autoclave were mixed to start the reaction under hydrothermal conditions. Hydroxyapatite crystals prepared at high temperatures above 150°C by this technique grew larger with higher aspect ratio than those obtained at the same temperature from the gel prepared by mixing the two solutions at room temperature.
