 Title    Kristallographisches und spektroskopisches Verhalten einiger gemischter Phosphat/Vanadat-Fluoroapatite Crystallographic and Spectroscopic Behaviour of Some Mixed Phosphate/Vanadate Fluoroapatites  
 Abstract    Crystallographic data for m ixed phosphate/vanadate fluoroapatites o f the type M 1o(P0 4)6_J(V 0 4)AF2 (with M = Ca, Sr, Ba and x = 1—3) have been obtained from X-ray powder data. The only structural effect observed is a continuous increase of unit cell dim ensions with increased vanadate incorporation. The IR and Raman spectra show that the V 0 43 incorporation has a negligible effect on the strength of the P —O bonds, although a small bond weakening for both tetrahedral oxoanions is observed as the unit cell volum e increases. The results are com par­ able to those reported earlier for similar mixed hydroxyapatites and suggest that the fluoroapatite lattice can be considered as a good "m odel" for the vertebrate hard tissues.
