Two routes for obtaining calcium phosphates by sol-gel technique are described. The ceramic precursors were calcium nitrate [Ca(NO3)2∙4H2O] and acid ammonium phosphate [(NH4)2HPO4]. The ammonium hydroxide (0.5 molar) was added in the solution in order to stabilize the pH to 9, approximately. The samples were analyzed by scanning electron microscopy with (SEM), X-ray diffraction (XRD) and Infrared spectrum (FTIR) to assess the morphology of the sintered powders, as well as present phases and… CONTINUE READING
