Synthesis and characterization of β-TCP/HA nanocomposite: Morphology and microstructure

Abstract

β-Tricalcium phosphate (β-TCP)/hydroxyapatite (HA) nanocomposite have been synthesized by the precipitation method. Then, the effect of change in weight percentage, temperature, stirring time, pH, and surfactant on β-TCP/ HA nanocomposite powders were studied. The samples were characterized by different techniques such as X-ray diffraction, Fourier transform infrared spectra, and scanning and transmission electron microscopy techniques. The results showed that using a chemical deposition method, β-TCP/HA nanocomposite with uniform size and particle size distribution could be obtained. SPAN 20 had better results as a surfactant compared to Aliquat. In general, samples were optimized in a pH of 10, with 24-h stirring time, temperature of 1100°C, and concentration of 0.3 molar calcium salt and 0.19 molar salt phosphate.
