β-wollastonite (βW) has sparked much interest in bone defect recovery and regeneration. Biomaterial-associated infections reactions between implants with human cells have become a standard clinical concern. In this study, green synthesized βW, from rice husk ash calcined limestone precursor, was incorporated mullite, maghemite, silver to produce β wollastonite composite (βWMAF) enhance the tensile strength antibacterial properties. The addition of mullite βWMAF increased compared βW. vitro...
The morphology and surface topography of calcium silicate coated on Ti6Al4V implant were studied using field emission scanning electron microscopy (FESEM) X-ray diffraction analysis (XRD) respectively. titanium alloy plates was mechanically ground with 320, 800 1200 grits SiC abrasive paper followed by polishing into mirror-like finish. synthesized β-CaSiO 3 deposited onto the substrate beam evaporator. After coating, heat treated at 500 °C for 1 hour. Characterization e-beam evaporation...
Bioactive composites consist of pseudowollastonite and mullite synthesized from natural resources was developed for bone implant applications.To realize such applications, a mechanical test these in vitro bioactivity SBF solution were studied.The present paper reports the rice husk ash limestone reinforced with 10, 20 30 wt. % mullite.Influence sintering temperature, phase composition, morphology towards properties various pseudowollastonite-mullite (PSW-M) examined prior to test.It found...
Barium titanate with 10% barium ferrite substitution (BaTiO 3 -BaFe 12 O 19 ) has been synthesized by the solid state reaction route. Formation of BaFe phase confirmed its existence in composite. Impedance spectroscopy study composite sample was performed at different temperatures 25, 40, 80, 120 and 160 °C. substituted shows a single semicircle lower temperature two overlapped arcs °C due to grain boundary. The impedance plots were fitted based on parallel R-CPE circuit. boundary resistance...
Barium ferrite-barium titanate composite systems, (1-x)BaFe12O19 − (x)BaTiO3 with different weight fractions of × = 0.0, 0.1, 0.3 and 0.5 were prepared via the conventional solid state reaction method using nano-sized starting materials. The x-ray diffraction peaks samples show two phases which can be indexed by hexagonal barium ferrite tetragonal titanate. Field emission scanning electron microscope (FESEM) image sample 0.1 shows formation BaTiO3 grains spreading evenly among micron-sized...
