Sodium-carbonate co-substituted hydroxyapatite ceramics
Powders of sodium-carbonate co-substituted hydroxyapatite, having sodium content in the range of 0.25–1.5 wt.% with a 0.25 wt.% step, were prepared by a precipitation-solid state reaction route. Compacts of the powders were sintered in a CO2 flow (4 mL/min) at 1100 °C for 2 h. The sintered ceramics contained sodium and carbonate ions in the ranges of 0–1.5 wt.% and 1.3–6 wt.%, respectively, whi...
متن کاملNovel Patterning of Silicon-Substituted Hydroxyapatite
Template-assisted electrohydrodynamic atomisation (TAEA) spraying of nanometer-sized siliconsubstituted hydroxyapatite (nanoSiHA) was used to pattern implant surfaces for guided cell growth to improve the repair and regeneration of medical implants. A suspension of nanoSiHA was prepared and characterized. Patterns of pillars and tracks of various dimensions were prepared using the suspension. I...
متن کاملSilicon-substituted hydroxyapatite nanocomposite: Synthesis, characterization and in vitro bioactivity study in Human Serum Albumin
Nano hydroxyapatite and Silicon-substituted hydroxyapatite nanocomposites with various amount of Si contents (0, 2, 4 and 6 mole % as named as HS0, HS2, HS4 and HS6) were prepared via in situ hybridization method and were analyzed by XRD, FTIR, SEM and AFM techniques. Size distribution of the products demonstrated that hydroxyapatite particles size was between 2 and 53.5 nm with further mean si...
متن کاملHydroxyapatite and Hydroxyapatite-Based Ceramics
Data are summarized on the synthesis of hydroxyapatite (HA) by wet-chemical processes, solidstate reactions, and hydrothermal treatment. The conditions for HA preparation via precipitation from solutions of calcium chloride, dibasic ammonium phosphate, and aqueous ammonia are discussed at length. Detailed analysis of the fabrication and properties of calcium-phosphate-based ceramics is presente...
متن کاملHigh Biological performance of Silicon Substituted Nano Hydroxyapatite Synthesized in Simulated Body Fluid at 37°C
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...
