摘要: Abstract One-step mechanochemical process followed by thermal treatment has been used to produce calcium phosphate-based composite nanopowders. Effects of milling and subsequent heat on the phase transition as well structural features were investigated. The products characterized powder X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, scanning electron microscopy (SEM), energy dispersive spectroscopy (EDX), transmission (TEM) techniques. results revealed that dominant phases after mechanical activation hydroxyapatite, anatase (TiO 2 ), periclase (MgO), while annealing at 700 °C hydroxyapatite along with geikielite (MgTiO 3 ) (MgO) major phases. In addition, decomposition tricalcium phosphate (β-TCP) occurred in range 900–1100 °C which resulted formation Evaluation samples calculated profiles analysis indicated average crystallite size 10 h about 21 34 nm, respectively. TEM SEM studies exhibited considerable morphological changes temperatures ≥900 °C had be ascribed not only grain growth, but also for transformation β-TCP.
