Self-Toughness Porous Sodium Titanate Bioceramics Prepared via In Situ Grown Na2Ti6O13 Rods
Here in, we report the porous bioceramic with Na2Ti6O13 rods prepared by in-situ growth method.The samples were prepared using cold uniaxial pressing (40 MPa) technique and further sintered at different temperatures.The structure and morphology were characterized by XRD and SEM.The porosity, compressive strength and fracture toughness were also investigated.The bonelike apatite deposition ability of the fabricated ceramic samples was evaluated by Kokubo simulated body fluid (SBF) soaking method.The results indicated that the Na2Ti6O13 rods with about 1-3 μm in diameter are uniformly distributed in the self-toughness porous sodium titanate ceramics (SPSTC).The SPSTC with a porosity of 61.10±1.12 % exhibits good compressive strength (43.36±2.43 MPa) and fracture toughness (3.47±0.21 MPa·m1/2).The results indicate that the novel SPSTC scaffolds are promising for bone tissue engineering applications.
