Phytic acid derived bioactive CaO-P2O5-SiO2 gel-glasses. Journal of materials science. Materials in medicine, 2011, Volume: 22, Issue:12 The possibility of using phytic acid as a precursor to synthesize CaO-P(2)O(5)-SiO(2) glasses by sol-gel method has been explored and the pseudo ternary phase diagram has been established. It was shown that gel-glasses over a broader range of compositions could be prepared compared to other phosphorus precursors or melt-quenching method. Furthermore, phytic acid was found to assist calcium being incorporated into glass networks. In vitro tests in simulated body fluid (SBF) were performed on the above gel-glasses and it was found that they were bioactive over a much broader compositional range especially at high phosphate content, thus enabling one to design bioactive materials with various degradation rates by adjusting the phosphate content.

Microstructural study of aerosol-gel derived hydroxyapatite coatings. Biomolecular engineering, 2002, Volume: 19, Issue:2-6 Highly porous aerosol-gel derived hydroxyapatite (HAP) coatings have been prepared from calcium nitrate and phosphoric acid based sols. Precursor solutions were prepared by filtering the suspension formed during the ultrasonic slurring of the reactants mixture. The coatings deposited on Si wafers were studied after sintering at different temperatures by using Fourier transform infrared spectroscopy, X-ray diffraction, energy disperse microanalysis and scanning electron microscopy. The composition, structure and morphology of the coatings sintered at 650 degrees C were found to fit highly porous HAP. That is considered of great relevance since the deposition parameters are compatible with the processing of bioactive coatings on load bearing metallic substrates. Topics: Aerosols; Calcium Compounds; Coated Materials, Biocompatible; Durapatite; Gels; Hot Temperature; Materials Testing; Microscopy, Electron, Scanning; Nitrates; Phosphoric Acids; Sensitivity and Specificity; Silicon; Spectroscopy, Fourier Transform Infrared; Surface Properties; X-Ray Diffraction	2002
