| description | SUMMARY
Manganese doped biphasic calcium phosphate
powders have been synthesized via sol-gel method.
The powders are of nanosize and high crystallinity.
Dense pure BCP and Mn-doped BCP ceramics were
fabricated via uniaxial pressing using the sol-gel
derived powders. The compacted discs were sintered
in air atmosphere with temperatures ranging from
1000 ºC to 1400 ºC. The presence of manganese
improves the densification in the BCP mixture as the
relative density increased with Mn doping and also
sintering temperature. Considerable grain growth has
been observed at 1300 ºC for Mn-doped BCP samples
compared to the pure BCP. Furthermore, 15 mol%
Mn showed the maximum hardness value of 6.66 GPa
at 1400 ºC compared to pure BCP of only 2.89 GPa.
Similarly, the Mn-doped BCP has superior fracture
toughness where it attained maximum values of 1.05
MPam1/2 at 1400 ºC compared to 0.72 MPam1/2 at
1300 ºC of pure BCP. |
