Ca²⁺  \(\to\)  Cu²⁺  exchange in synthetic hydroxylapatite is facilitated by an increase in Cu²⁺ concentration, a decrease in pH of the medium of exchange and in the particle size of hydroxylapatite. Adsorption of  Cu²⁺ and its accompanying diffusion into the interion of the crystals of  hydroxylapatite explain the mechanism of exchange.
