In this paper, crystallization comparison of three amorphous phase nanopowders – calcium carbonate, tricalcium phosphate and hydroxyapatite – has been showed with the intention to design biomaterials with controlled and improved properties. Thermal analysis was carried out using thermogravimetry (TGA), differential thermal analysis (DTA) and evolved gas analysis (EGA). Heated powders were characterized by X-ray diffraction, ultra small angle X-ray scattering (USAXS), small angle X-ray scattering (SAXS) and wide angle X-ray scattering (WAXS) to determine structural changes during heating. As a complementary method for characterizing chemical phases and functional groups Fourier transform infra-red spectroscopy (FTIR) was performed.
