Sintering and properties of dense manganese-doped calcium phosphate bioceramics prepared using sol-gel derived nanopowders

Dense manganese-doped biphasic calcium phosphate (Mn-BCP) ceramics were fabricated via uniaxial pressing using the sol-gel derived powders. The compacted discs were sintered in ambient atmosphere with temperatures ranging from 800C to 1400C. Manganese (Mn) level was varied in the range of 0.6, 1.9,...

Furthermore, 11.9mol% Mn-doped BCP dense samples showed the maximum hardness of 6.66GPa compared to 2.89GPa for the undoped BCP.
