Preparation and Characteristics of Strontium Containing Bioactive CaSiO3 Ceramics


Article Preview

Strontium(Sr) containing CaSiO3 powders were synthesized using chemical precipitation. X-Ray Fluorescence (XRF) analysis confirmed the incorporation of Sr in CaSiO3. X-Ray diffraction (XRD) analysis revealed that the incorporation of Sr into the lattice structure of β-CaSiO3 powders, does not change its β-phase composition. The lattice dimension of β-CaSiO3 powders increased with the increase of Sr contents (0-10% Sr). Sr-CaSiO3 ceramic disk were prepared from the Sr-CaSiO3 poweders by uniaxial pressing at 150 MPa and sintering at 1100°C for 3h. XRD and Differential Thermal Anaysis (DTA) analysis indicated that there is a correlation betweem Sr concentration (0-10% Sr) and the phase transition from β-CaSiO3 to α-CaSiO3 with the increase of Sr contents. This transition was promoted by the decrease in temperature.
