“…Manganese (Mn) is one of the proposed additives. The presence of Mn ions in the CaHap structures leads to change in biological and chemical properties of the CaHap material 20,21 . From biological point of view, Mn is an important component on the synthesis of mucopolysaccharides-compounds responsible for cartilage formation.…”

Colloidal manganese (Mn)-doped calcium hydroxyapatites (abbreviated as MnHap) were prepared by the coprecipitation method. The Mn/(Ca+Mn) atomic ratio in the solution (abbreviated as XMn) was varied from 0~0.30. The precipitated particles were characterized by various physicochemical analyses, i.e., TEM, XRD, N2 and H2O adsorptions, TG, FTIR, ICP-AES and XPS measurements. The MnHap particles were produced at 0.01≤XMn≤0.2. The calcium hydroxyapatite produced without Mn ions (XMn=0) was rod-like particles with 23 nm (width) x 55 nm (length). With increase in XMn up to 0.06, the particle width was decreased. The thickness of the rod-like particles produced at XMn≥0.08 was further decreased to ca. 3~5 nm. The spherical nano-particles with ca. 7 nm in diameter precipitated at XMn=0.3 were -TCP and amorphous particles of -MnOOH precursor. The particle color was varied from white to brown, dark-brown and pale-red. The ICP-AES measurement revealed that all the MnHap particles are cation-deficient with XMn values among 1.52~1.63. The lattice constants of c-axis was decreased with increase in XMn at XMn≥0.05 by incorporation of Mn(III) and Mn(IV) ions with smaller atomic radii, 0.072 and 0.053 nm, respectively, instead of Mn(II) ones (0.089 nm). The XPS measurement also revealed that there is no Mn(II) in the MnHap particles but they include both Mn(III) and Mn(IV) ions. The in vacuo IR measurements suggested that the incorporation of Mn ions increased the acidity of surface P-OH groups.

“…3),4) Although influence of Mn on stability and particle growth of HAp 5) and some studies with electron paramagnetic resonance (EPR) on Mn incorporation in HAp 6) and b-TCP 7) have been done, local environment of Mn ions in b-TCP has not yet been clearly understood in an atomic scale. In the present study, local environment of Mn ions in b-TCP is investigated in an atomic scale by the NEXAFS technique with the aid of the first principles calculations.…”

Mn-doped b-tricalcium phosphate (b-TCP) is synthesized by the solid-state reaction method. The local environment of doped Mn ions in b-TCP is investigated by the near-edge X-ray absorption fine structure (NEXAFS) measurements. The first principles calculations are also carried out to obtain the theoretical NEXAFS spectra within the density functional theory (DFT). Observed NEXAFS spectra from the Mn ions in b-TCP are quantitatively well reproduced by the present theoretical calculations, which show Mn ions are substituted for Ca 2＋ site in b-TCP.
