Barium titanate/hydroxyapatite (BT/HA) spherical nanocomposites were fabricated by hydrothermal process using HA nanopowders dispersed in BT precursor solution. The samples were characterized by XRD, SEM and TEM to obtain sizes and crystal structure. The results showed that the BT/HA spherical nanocomposites can be obtained at 120–180 °C for 12 h and the morphology is HA nanopowders of 20–30 nm growth on the surface of spherical structure BT nanoparticles with diameter of 100–150 nm. The BT/HA spherical nanocomposites obtained at 160 °C for 12 h has the ε value and compressive strengths were 2.98 and 39.15 MPa, respectively. A growth mechanism was also proposed to account for BT/HA spherical nanocomposites. Moreover, the biotoxicity of nanocomposites show that the BT/HA materials is non-toxic to the MSCs cells.
