Tin Oxide was obtained from the thermal decomposition of tin oxalate at 800 deg C for one hour. The precursor was precipitated at room temperature from the reaction of aqueous solutions of 0.04 M tin (II) chloride and 0.04 M oxalic acid. X-ray diffraction data of the calcined powder showed that it consisted of high purity tetragonal SnO2. Examination using a field emission scanning electron microscopy (FESEM) showed that the individual particles were spherical in shape, with a mean diameter of ~75nm. De-caking with a mortar and pestle of the calcined powders in the presence of atmospheric water vapour caused agglomeration.
