Investigations of the effects of initial Zn concentration and sintering conditions on the phase behavior and mechanical properties of Zn-doped bcp

Sintering behaviour of zinc doped biphasic calcium phosphate was investigated over the temperature range of 1000–1300oC. The starting powders have been synthesized through Sol-Gel method. Zinc concentration was varied in the range of 0, 1, 2, 4, 5, 10 and 15mol%. After uniaxial pressing followed by...
