Manganese doping on biphasic calcium phosphate ceramics for machanical improvement

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 si...
