Abstract
In this work, nanoscale zinc substituted calcium phosphate ceramics substituted were synthesized by simple precipitation method, performed under alkaline solution of pH 10. Three different zinc concentrations (5%, 10% and 15 mol%) were incorporated into calcium phosphate ceramics with experimental ratios of (Ca+Zn)/P were all maintained at 1.67 for easier comparison. The phase composition and lattice parameters for each sample were determined by using X-ray diffraction (XRD) method. Other characterization techniques such as Fourier transform infrared (FTIR) and field emission scanning electron (FESEM) were also utilized to investigate material’s molecule internal bonds properties and powders morphology, respectively. Based on XRD results, zinc ions addition disturbed the calcium phosphate ceramics structure causing its crystallite size to become smaller as the amount of zinc increased. After the powders undergo calcination process, the bands of PO4 in its FTIR spectra increased while the H2O bands decreased. FESEM results showed that the powders are uniform but irregular in shape and tend to agglomerate with increasing zinc fraction.
