摘要

The apparent transition temperature (T_c) and enthalpy (ΔH) of monoclinic (P2₁/b) ↔ hexagonal (P6₃/m) reversible phase transition in stoichiometric (Ca/P = 5/3) hydroxyapatite were investigated as a function of heating/cooling rate by means of a differential scanning calorimeter (DSC), in the heating/cooling rate range of 0.5-3.0 K/min. The apparent T_c value slightly increased and decreased with increasing heating and cooling rates, respectively, while the apparent ΔH value was almost same within the experimental error.
