Structural properties of apatites from Finland studied by FTIR spectroscopy

Abstract

Studies by XRD and FTIR analyses of the structure of Sokli and Siilinjärvi apatites and a comparison with the Kola and Kovdor apatites are presented. In the structure of apatites from Finland the occurrence of F...OH and F...OH...F bonds and the incorporation of (CO3)2- ions into A and B positions were established.
