Abstract
Solid solutions of cadmium and calcium hydroxyapatite
[ Ca
Cd
(PO4)6(OH)2 (0 
x 10)] were
synthesized by a wet process in a basic medium. The lattice dimensions of
these compounds vary linearly with the atom percent cadmium. The
distribution of the calcium and cadmium ions between two non-equivalent
crystallographic sites, (1) and (2), were determined by the Rietveld method.
The site-occupancy factors of atoms indicate a slight preference of cadmium
for site (2) in the apatite structure.
