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 800�C to 1400�C. Manganese (Mn) level was varied in the range of 0.6, 1...
