Sol-gel derived zinc doped calcium phosphate bioceramics prepared via different sintering strategies

Sinterability of zinc doped calcium phosphate (CaP) sintered via conventional pressureless and two step sintering methods was investigated. The starting powders have been synthesized through sol-gel method with zinc concentration varied in the range of 0, 1, 4, and 10mol%. After uniaxial pressing...
