Abstract

Society is constantly facing new challenges, especially with
regard to bone reconstruction and restoration with the increase in
accidents and wars, so attention to biocompatible and absorbable
materials became an urgent necessity, in this research a
nanocomposite consisting of hydroxyapatite (HA) and
polyvinylpyrrolidone (PVP) was addressed as a compound.
Biocompatible, as the compound was formulated with a HA / PVP
ratio 3.6-14.5 by chemical precipitation process of solutions of
calcium nitrate and ammonium hydrogen phosphate in PVP
solution. The compound was thermally treated, the micro-crystal
structure and the phase composition, the size of the coherent
scattering regions (CSR) and the swelling property of the
compound were studied. The shape and size of HA were
determined. In addition, the compound was exposed to a laser
beam with a wavelength of 355 nm and the resulting spectrum
using Electron paramagnetic resonance (EPR) technology was
studied.
