Abstract

Calcium hydroxyapatite (HAP) Ca10 (PO4) 6 (OH) 2 is an important material, which is
applied in reconstruction of human solid tissue. In medicine, artificial materials based on HAP are
used as ceramics and composites for recovering of bone and teeth, and as implant coatings for better
integration of synthetic materials with hydroxyapatite of human solid tissue.
Phase and elemental composition of HAP samples by XRD and EPMA data has shown that under
certain conditions method of chemical precipitation from solution calcium-deficient hydroxyapatite
CDHAP could be produced with the calcium to phosphorous ratio Ca/P = 1.43.
XRD analysis proved that all of the samples consist of nanocrystals with the average size of ~ 50 nm.
The obtained data show that the calcium deficiency in the crystal lattice of HAP is kept when calcium
atoms are substituted by of Zn and Cu atoms.
Partial substitution of calcium by Zn and Cu atoms of the radii less then calcium radius leads to the
decrease of HAP cell unit parameters and reducing of nanocrystals average size
