Tin dioxide nanoparticles were synthesized by sol-gel method and calcined at different temperatures in the range 350-750°C. The SnO_2 precursor solution was prepared from SnCl_2 ·2H_2O (tin (II) chloride dihydrate), and chloride ions were removed from the solution before the sol-gel synthesis was applied. SnO_2 powders were characterized by thermal analyses, X-ray diffraction, field emission gun-scanning electron microscopy, and energy dispersive X-ray spectroscopy, and grain size of nanoparticles were determined by using the Debye-Scherrer formula.
