Abstract :
The results of a comparative study of amorphous (Na, CO3)- and (K, CO3)-containing apatites by TPM MS analysis, FTIR, XRD, SEM and EPR are presented. Annealing of amorphous apatite at temperatures below 400°C does not lead to changing of nanoparticle shape and size and an extent of its crystallinity. A significant difference in the formation of γ-induced defects in (Na, CO3)- and (K,CO3)-containing apatites was found.
