Abstract

Nanocrystalline SnO₂ was synthesized by direct mixing and grinding of SnCl₄·5H₂O and NaOH at room temperature, followed by calcination at different temperatures for different times in air. Product samples were characterized by X-ray diffraction and transmission electron microscope, revealing that the amorphous precursor SnO₂ was transformed to crystals at 200 °C for 3 h, and that the average particle size increased upon raising the calcining temperature or prolonging the calcining time. The mechanism of the phase transformation of the products is discussed.
