Zinc-dopedbiphasic calcium phosphate (BCP) powders have been synthesized via sol-gelmethod. The dopant concentration ions were adjusted at 1, 2, 3, 5, 10 and 15mol%. The powders have been calcined at varying temperatures ranging from500-900 °C and then characterized by XRD, FTIR, TG/DTA, TEMand FESEM data. X-raydiffraction patterns show that the phases present in Zn-doped BCP arehydroxyapatite, β-TCP andparascholzite. FTIR analysis revealthat the separation of three PO43-stretching peaks is obscure and OH bending peak at 630 cm-1 broadenwith an increase in Zn concentration, whereas the PO43- band of TCP at 1085 cm-1 is sharper at higher calcinationtemperatures. Morphologyanalysis show that the size of agglomerates tends to increase with theincreasing Zn concentration. These findings indicate that an increase in Znlevel doped to the BCP affects the phase composition, crystallization and microstructureof the samples.
