The structure of apatites allows large variations of composition given by the generic formula (M10(XO4)6Z2) including partial or complete substitution of both the cationic as well as the anionic sites, formation of nonstoichiometric forms and solid solutions. More than half of naturally occurring elements can be accommodated by apatite structure in a …
