Resumen:
A simple and non-expensive procedure was performed to synthesize
hydroxyapatite (HAp) flake-like nanostructures, by using a
co-precipitation method with tannic acid as stabilizing agent at room
temperature and freeze drying. Samples were synthesized with two
different salts, Ca(NO3)(2) and CaCl2. X-ray diffraction analysis, Raman
spectroscopy, scanning and transmission electron microscopy
characterizations reveal Ca-10(PO4)(6)(OH)(2) HAp particles with
hexagonal structure and P63/m space group in both cases. In addition,
the particle size was smaller than 20 nm. The advantage of this method
over the works reported to date lies in the ease for obtaining HAp
particles with a single morphology (flakes), in high yield. This opens
the possibility of expanding the view to the designing of new composite
materials based on the HAp synthesized at room temperature.
