The effect of a preliminary mechanochemical activation of the components in
the Ca-10(PO4)(6)(OH)(2) solid-phase synthesis from the CaO + CaHPO4 and C
aCO3 + (NH4)(2)HPO4 was studied. The crystallographic parameters of the pro
ducts, their spectroscopic and dielectric characteristics were determined.
The effect of the composition of the initial components on the rate of the
synthesis was examined.
