Abstrakt:
The main objective of this work is the synthesis of hydroxyapatite powder with a general
formula Ca10(PO4)6(OH)2 by the precipitation method with the following synthetic
conditions: the Ca/P ratio = 1, the range of pH value = 7, where ammonia hydroxide
solution was used to adjust the pH, and the rate of precipitation of ammonium
dihydrogen phosphate was determined to 2 ml·min−1. Yet another aim of this paper was
to characterize the physicochemical properties of the hydroxyapatite phase and
subsequently to evaluate the effect of firing temperatures on the hydroxyapatite
structure. The synthesized powder was characterized by X-ray diffraction (XRD) in
order to identify the phase composition and crystallinity; the morphology of synthesized
powder having been studied by scanning electron microscopy (SEM) and the prepared
powder analyzed with respect to the particle size distribution (PSD).
