in this work, we report high biological performance of silicon substituted nano hydroxyapatite (nha) prepared by immersion of calcium phosphate and sodium silicate as precursors in simulated body fluid (sbf) solution for 24, 36, 48 and 72 hrs at 37°c. characterization and chemical analysis of the synthesized powders were performed by fourier transform, infrared spectroscopy (ft-ir), x-ray powde...

This study investigated the effects of a new strontium-doped bioactive glass and fluoride on hydroxyapatite crystallization. We designed an in vitro experiment with calcium phosphate (CaCl2·2H2O + K2HPO4 buffer solution) different concentrations (1 mg/mL or 5 mg/mL), (0 ppm, 1 ppm ppm). Tris-buffered saline served as negative control. After incubation at 37 ? for 48 h, shape organization crysta...

Solid titration was used to explore the solubility isotherms of partially (Srx-HAp, x=1, 5, 10, 40, 60 mol.%) and fully substituted strontium hydroxyapatite (Sr-HAp). Solubility increased with increasing strontium content. No phase other than strontium-substituted HAp, corresponding to the original titrant, was detected in the solid present at equilibrium; in particular, dicalcium hydrogen phos...
