| 摘 要： | Crystalline tin oxide nanoparticles were synthesized by the direct precipitation from the starting material granulated tin. TG-DTA of the precursor showed a heavy weight loss at about 130℃ accompanied by an endothermic peak， two exothermic peaks above 200℃ accompanied by small weight loss indicated the decomposition and the oxidation of residual NO3- ion and PEG. XRD showed that obtained particles agreed well with the determination result of bulk SnO2. The broadened XRD patterns became sharper as the calcining temperature turned to higher， it was indicated that the growth of the particle was exhibited. The surface area of the particles calcined at 300℃ was 161.1m2·g-1 and declined as the calcining temperature turned to higher. TEM showed an heavier agglomeration at higher temperature.
