| 摘 要： | Nanocrystalline SnO2 was synthesized by direct mixing and grinding of SnCI4-5H2O 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℃ for 3h, 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.
