Abstract
In this paper, we present the preparation and electrical properties of
nanocrystalline powders of hydroxyapatite (HAP) bioceramics, produced
using the starting materials Ca(H2PO4)(2), Ca(OH)(2) and a high energy
dry ball milling technique. Titanium calcium phosphate (CaP-Ti) was also
prepared, the raw materials Ca(H2PO4)(2) and TiO2, and examined. The HAP
was obtained of milling 5, 10 and 15 h while in the reaction with
CaP-Ti, the CaTi4P6O24 phase was obtained after 5, 10 and 15 h of
milling. The HAP and the ceramic calcium phosphate with titanium
(CaP-Ti) were studied by X-ray powder diffraction, DC and AC
conductivity and dielectric constant measurements. (c) 2006 Elsevier
