Abstract
Simultaneous temperature-programmed desorption, mass spectroscopy, and thermogravimetry (TPD-MS-TG) were carried out to explore the evolution process of H2O and CO2 from calcium hydroxyapatite particles containing carbonate ions of 0.1-10.1 mass%. The TPD-MS curves of both H2O and CO2 exhibited two peaks: desorption of H2O and CO2 adsorbed on the particles below 600 degrees C, and liberation of H2O and CO2 in the crystals above 700 degrees C. The increase of carbonate ion content in the particles increased the weight loss in the TPD-TG curves.Entities:
