| Summary: | The effect of Manganese (Mn) addition on the Vickers
hardness and relative density of nanocrystalline
hydroxyapatite (HA) dense bodies were studied. The starting
Mn doped HA powders was synthesizedv ia sol-gel method
with Mn concentrationv ariesf rom 2 molo/ou p to 15 mol% Mn.
The Mn doped HA disc samples were prepared by uniaxial
pressing at 200MPa and subsequently sintered at 1300oC.
Characterization was carried out where appropriate to
determine the phases present, bulk density, Vickers hardness
of the various content of Mn doped HA dense bodies. The
addition of Mn was observed to inf luence the color
appearanceo f the powdersa nd denseb odiesa s well. Higher
Mn concentrationr esultedi n dark grey powders. lt was also
found that the hardness and relative density of the material
increaseda s the Mn content increaseda nd influencedb y the
crystallinity of the prepared Mn doped HA powders. |
