Strontium carbonate (SrCO3) nanostructures were synthesized via simple hydrothermal method by Sr (NO3)(2), ethylenediamine and hydrazine as reagents. The products were characterized with X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX) and Fourier transform infrared spectroscopy (FT-IR). Different parameter's effects on the product size and morphology were investigated. It was found that reagent concentration, reaction time and temperature play key roles in morphology of the obtained product.
