Abstract

Abstract: Unique nanosized designed ceramic powders, Fe-doped hardystonite (Fe-HT) with the chemical composition of Ca1.85Fe0.15ZnSi2O7 (0.15Fe-HT) and Ca1.75Fe0.25ZnSi2O7 (0.25Fe-HT), were synthesized by the sol–gel method in order to develop a multifunctional bioactive powder for hyperthermic and tissue engineering applications. Characterization techniques such as X-ray diffraction analysis, transmission electron microscopy, Fourier transform infrared spectroscopy and energy-dispersive X-ray spectroscopy were used to investigate the structural characterization of the obtained powders. The results showed that nanocrystalline single-phase Fe-HT powders were successfully synthesized by sol–gel method. The prepared nanopowders had structural properties such as crystallite size (~53 nm), crystallinity degree (~55 %) and lattice strain (~0.355 %) for 0.15Fe-HT and crystallite size (~40 nm), crystallinity degree (~41 %) and lattice strain (~0.401 %) for 0.25Fe-HT. The obtained Fe-HT nanopowders are expected to be a suitable candidate for tissue engineering and also hyperthermia-based cancer therapy.
