| 摘 要： | 通过水热法，使五水四氯化锡在氨水的环境中合成纳米级的二氧化锡微粒。采用冷冻干燥法得到粉体。使用XRD对实验合成的产物进行一系列的分析，结果发现所得的二氧化锡粉体基本为四方晶系（即金红石型）。纳米二氧化锡微粒有近球形，棒状，椭球形等的形貌，其粒径范围从4nm到120nm。本实验主要研究以下几个因素对二氧化锡粉体形貌的影响：溶液的浓度、合成温度、合成时间及溶液pH值。

| Abstract: | With ammonia and tin tetrachloride pentahydrate as raw hydrothermal synthesis SnO2 particles. Powder obtained by freeze -drying method. On tin dioxide powders synthesized products were characterized by XRD analysis showed that the powder is tetragonal （also known as rutile）. Tin dioxide nano-particles with particle size ranging from 4nm to 120nm nearly spherical, rod, etc. ellipsoidal shape. This study solution concentration, synthesis temperature, and synthesis time factors of pH tin dioxide powder morphology. |
