摘要

The SnO_2 powders have been prepared by hydrothermal method at temperatures of 150, 180°C from SnCl_2·2H_2O, NaOH and sulfur (S) powder. The phases and morphology of the products were analyzed by X-ray diffraction (XRD) and transmission electron microscopy (TEM) respectively. Experimental results show that, no impurity phases were found except SnO_2 and no regular geometric shapes were observed in this product powders. The reaction mechanism is that SnO_2 may be obtained by decomposition of Na_2SnO_2 formed from Sn(OH)_2+NaOH.
