Ti(IV)-substituted calcium hydroxyapatite (Ti-CaHap) microparticles were synthesized by hydrolyzing the phenyl phosphate (C 6 H 5 PO 4 H 2 ) in a mixture of aqueous Ca(OH) 2 and Ti(SO 4 ) 2 solutions at pH=8 and 85°C. Then, the atomic ratio Ti/(Ca+Ti) in the starting solution was ranged from 0 to 0.20. The XRD pattern of the product formed at...
The present study synthesized five types of hydroxyapatite (Hap) particles containing light rare earth ions (Ln 3+ : La 3+ , Ce 3+ , Pr 3+ , Nd 3+ and Sm 3+ ) and Ca 2+ ions from aqueous solutions with different Ln/(Ln+Ca) atomic ratios ([X Ln ]) ranging from 0 to 0.15. The crystal phases of the products and their inner and surface structures...
