摘　　要：本文采用共沸蒸馏法、水热法、溶胶-凝胶法分别制备纳米SnO2粉体,所制得的SnO2粉体利用X-射线衍射(XRD)和扫描电子显微镜(SEM)表征。结果表明,3种方法制备得的粉体均为四方金红石结构,共沸蒸馏法所得粉体平均颗粒约为20nm。水热法所得粉体的平均颗粒约为10nm。溶胶-凝胶法所得粉体的平均颗粒约为70nm。研究不同制备方法合成纳米SnO2粉体在合成工艺,生产周期,产物颗粒大小等方面的优缺点。In this paper, Nanometer Tin Oxide Powders was synthesized with three methods by azeotropic dis- tillation,sol-gel technique and hydrothermal synthesis. The obtained nano-partiele was characterized by X-ray diffraction（XRD） and scanning electron microscopy（SEM）. The results showed that the namometer tin oxide par- ticle were tetragonal rutite structure. The size of particles which synthesized by azeotropie distillation was about 20nm and which prepared by hydmthermal method wans about 10nm. The diameter of the particles synthesized by sol-gel technique are up to 10nm. The advantages and disadvantage of prepared by different aynthetic methods in synthesis technology, productive cost, the size of the produtive particles were studied.
