Abstract
In this work, novel BCP (β-CPP, β-Ca2P2O7/β-TCP, β-Ca3(PO4)2) bioceramics have been synthesized by wet chemical precipitation using lime mud waste from cellulose industry as inexpensive sustainable CaCO3 precursor source. The synthesized BCP bioceramics have been characterized regarding to X-ray diffraction (XRD), Rietveld refinement, scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FTIR). The results indicated that the amounts of the phases β-CPP and β-TCP in the biphasic mixtures depend on the different HNO3 molar concentrations used in the synthesis. In addition, the BCP (β-CPP/β-TCP) powders exhibited average crystallite size in the range of 55.56 to 59.85 nm. Such novel BCP nanopowders produced by using CaCO3 from lime mud waste have high potential for biomedical applications.
