Dense manganese doped biphasic calcium phosphate for load bearing bone implants

Dense pure biphasic calcium phosphate (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. All powders have been proved to show HA and β-TCP phas...
