Preparation of nanostructured manganese-doped biphasic calcium phosphate powders via sol–gel method
Biphasic calcium phosphate ceramics doped with manganese (Mn-doped BCP) were prepared by using chemical doping via sol–gel technique. Four different concentrations of manganese (2, 5, 10, and 15 mol%) have been successfully incorporated into biphasic calcium phosphate (BCP) phases. X-ray diffra...

Summary: | Biphasic calcium phosphate ceramics doped with
manganese (Mn-doped BCP) were prepared by using
chemical doping via sol–gel technique. Four different
concentrations of manganese (2, 5, 10, and 15 mol%) have
been successfully incorporated into biphasic calcium
phosphate (BCP) phases. X-ray diffraction analysis
revealed that the phases present in the Mn-doped BCP
powders are hydroxyapatite and β-tricalcium phosphate.
The Mn-doped powders are more crystalline than Mn-free
BCP powder as its crystallinity increased with increasing
Mn content. Fourier transform infrared spectrum corresponded
to this result as the peak resolutions of PO4 bands
are viewed with more intensity with the increased Mn.
Particle size analysis resulted in nanoscale particles for the
Mn-doped and Mn-free BCP powders. From field emission
scanning electron microscope observation, Mn-doped BCP
powders showed nanoscale individual particles but tightly
agglomerated into microscale aggregates due to progressive
fusion of particles. Hence, it can be concluded that Mn acts
as calcination additives of the BCP powders. |
