Structural, crystallographic and morphological properties of microwave-assisted growth of nano-apatite powders

In this study, we present the changes of structures, lattice parameters, crystallinity and morphologies of nano-apatite powders grown via dropwise mixing wet chemical precipitation with microwave treatment for fast synthesis of apatite powders using appropriate amounts of calcium and phosphorous precursors. FTIR, XRD and SEM/EDX were used to characterize the obtained powdered samples. Nano-sized low crystalline and stoichiometric apatite powders comparable to stoichiometric commercial apatite powders were successfully synthesized. The lattice parameters decreased for microwave-treated apatite powders prepared via dropwise addition of phosphorous precursors. The powders exhibited agglomerated nano-sized spherical grains surface morphology.
