Abstract: (2876 Views)
β-TCP/ HA nanocomposite powders were synthesized by precipitation method at 1100°C for 2 hours and the effect of different surfactants on the resulted nano-composite powders were studied. Crystal structure and the formed phases were studied with X-ray diffraction (XRD) and Fourier transform infrared (FTIR). Investigating the size and morphology of the particles and agglomeration of the powder were investigated by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). According to the results, at Ca/P=1.58, pH=10, concentration of 0.3 molar calcium salt and 0.191 molar phosphate salt, beta-tricalcium phosphate/ hydroxyapatite nano-composites with a uniform particle size distribution a ratio of 60 to 40 in molar was obtained. Also, Span 20 as a dispersant showed better dispersion of particles than Aliquat, and reduced the agglomeration of nanoparticles to each other and resulted in the formation of nano composite particles with a particle size of 40-50 nm.
