Fabrication and sintering behavior of zinc-doped biphasic calcium phosphate bioceramics

Dense bioceramics with improved mechanical properties have been prepared using sol–gel derived zinc doped biphasic calcium phosphate (BCP) powders. Zinc concentration was varied in the range of 0,1, 2, 4, 5, 10, and 15mol%. The compaction of the powders followed by sintering provided the dense cer...
