TPD-TG-MS Study of Carbonate Calcium Hydroxyapatite Particles

  • Published:
Calcified Tissue International Aims and scope Submit manuscript

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°C, and liberation of H2O and CO2 in the crystals above 700°C. The increase of carbonate ion content in the particles increased the weight loss in the TPD-TG curves.
