  Abstract:  The thermal stability over time of the pure and multisubstituted hydroxyapatite (HAP) pastes, doped with magnesium, silicon, strontium and zinc, synthesized using aqueous precipitation method were investigated by thermal analyses (TG-DTA). Results show high thermal stability of pure and multidoped hydroxyapatite pastes, up to 1000 oC and even after ageing for 1 year, making these pastes promising nano materials for medical applications.

Keywords: hydroxyapatite, doped hydroxyapatites, paste, thermal analysis
