Synthesis and Characterization of Neodymium(III) and Gadolinium(III)‐Substituted Hydroxyapatite as Biomaterials

Nanocrystalline hydroxyapatite (HA), Ca 10 (PO 4 ) 6 (OH) 2 , substituted with gadolinium(III) (Gd 3+ ) and neodymium(III) (Nd 3+ ) in different mole ratios (M added /Ca added = X M , 0.01, 0.05, 0.1, and 0.2), was synthesized by an ion‐exchange method. All samples had the single phase of HA except ... View More
