Abstract

Abstrcat SnO_2 nanodendritc were successfully prepared by pressure-thermalcrystallization method using SnCl_4·5H_2O as raw material. Microstructure and morphology of the prepared products had been characterized by means of transmission electron microscopy(TEM),selected area electron diffraction(SAED) and X ray diffraction(XRD). The results showed the particle has dendritc-like apparent structure. The dendrites have trunks with lengths of 3～5 μm and diameters of 100～200 nm. The lengths and diameters of their branches are about 5～8 μm and 10～40 nm, respectively. The mechanism of the formation of SnO_2 was simply proposed.
