Kinetic analysis of the dehydration of ACP (a) and HAp (b) upon annealing at three different heating rates in the DTA analysis: 10, 20 and 50 °C/min. Activation energies calculated from the slopes of the linear fits in three different models: Kissinger, Augis-Bennett and Ozawa. The goodness of the fit varied from R2 = 0.96 (Kissinger, ACP) to R2 > 0.99 (Augis-Bennett and Ozawa, HAp).
