Abstract

The hydroxyapatite (HA) is one of the most used materials in medical applications, due to its similarity with human bones. A chemical synthesis method, and the characterization by atomic force microscopy (AFM) and scanning electron microscopy (SEM), has been chosen in this paper. The surface study on nm scale and the surface topography were evaluated by using AFM with tapping mode. The size distribution of the grown spherulite was carried out by AFM, operating in non-contact mode. The SEM pictures of the grown spherulite crystals shows many spherical agglomerations and few crystallites of 0.1 μm in size with pores..
