Synthesis and Characterization of Nanostructured Calcium Phosphates: Colloidal Suspension Rheological Study

Abstract:

Calcium phosphates bioceramics are a broad class of biomaterials, known by properties like biocompatibility and bioactivity in living tissues. The aim of this paper was the synthesis by wet method and characterization of nanostructured calcium phosphate powders in the Ca/P ratio of 1.67molar and rheological evaluation of the colloidal suspension during the synthesis: suspension viscosity with variable shear rate. Morphological characterization was performed for the hydrated nanostructured calcium phosphate powder by scanning electron microscopy with field effect, crystallography by X-Ray diffractometry, chemical characterization by Fourier Transformed Infrared Spectroscopy. The results demonstrated that varying the shear rate has a direct influence on the viscosity values according to time. This result may contribute to the development of a synthesis methodology for nanostructured calcium phosphate powders.
