Substitution effect on the crystallographic structure in Ca10−xSrx(PO4)6F2 solid

solution were studied by X-ray diffraction patterns and Rietveld refinements. Full

potential electronic structure calculations based upon linear combination atomic

orbitals were also performed using the obtained crystallographic parameters.

Density of states modification and the charge transfer were estimated versus the

calcium content. According to the complex impedance method, ionic conductivity

changes were explained.
