【Abstract】 Nano crystal SnO 2·In 2O 3 binary powders were prepared from SnCl 4·5H 2O and In by sol gel method. By using differential thermal analyzer (DTA),X ray diffraction(XRD)and transmission electron microscope(TEM),its phase structure and pattern were analyzed. The results showed that the synthesized SnO 2·In 2O 3 is micro nano crystal and the principal crystalline form is SnO 2 structure. In addition, the form of micro crystal grain is approximately spherical and its size is between 5 and 20?nm. Moreover, In 2O 3 is non crystalline material.更多还原
