One of the most economical routes to obtain this material is the precipitation. In the present work, it was prepared syn thetic hydroxyapatite using the precipitation route, beginning with aqueous solutions of calcium nitrate (Ca(NO 3).4H 2O ) and ammonium phosphate (H 2(PO 4)NH 4). The effect of physical-chemical variables such as pH of the mixture, temperature, time of agitation and res t and heat treatment was evaluated. By means of the characterization of the samples obtaine d to different conditions, it was possible to conclude about the optimal variables to sy nthesize this material.
