The subject of this study was the synthesis of 12 chitosan-hydroxyapatite (CH:HA) composites with different contents of carbonate ions (CO3 2-), in two weight ratios of CH to HA (30:70 and 50:50), and two viscosities of CH (low [L] and high [H]). The

Hydroxyapatite (HA) enriched with strontium and boron ions was synthesized using two different methods: the precipitation method (Sr,B-HAw) and the dry method (Sr,B-HAd). Additionally, for the sake of comparison, the “pure” unsubstituted HA was p

Complementary information on water and hydroxyl groups in nanocrystalline carbonated hydroxyapatites from TGA, NMR and IR measurements

Autor: Waclaw Kolodziejski, Agnieszka Kaflak

Publikováno v: Journal of Molecular Structure. 990:263-270

A set of 10 nanocrystalline carbonated hydroxyapatites (CHA) was studied using TGA, NMR and IR methods. Particular attention has been directed on water and structural hydroxyl groups. Various their characteristics have been evaluated on the basis of
