Fabrication of naturel pumice/hydroxyapatite composite for biomedical engineering
BACKGROUND We evaluated the Bovine hydroxyapatite (BHA) structure. BHA powder was admixed with 5 and 10 wt% natural pumice (NP). Compression strength, Vickers micro hardness, Fourier transform infrared spectroscopy, scanning electron microscopy (SEM) and X-ray diffraction studies were performed on the final NP-BHA composite products. The cells proliferation was investigated by MTT assay and SEM...
متن کاملSodium-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 کاملSynthesis, characterization and modelling of zinc and silicate co-substituted hydroxyapatite
Experimental chemistry and atomic modelling studies were performed here to investigate a novel ionic co-substitution in hydroxyapatite (HA). Zinc, silicate co-substituted HA (ZnSiHA) remained phase pure after heating to 1100 °C with Zn and Si amounts of 0.6 wt% and 1.2 wt%, respectively. Unique lattice expansions in ZnSiHA, silicate Fourier transform infrared peaks and changes to the hydroxyl 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...
