Nanoparticles of tin oxide (SnO2) have been prepared from water-in-oil microemulsions consisting of water, AOT (surfactant), and n-heptane (oil). Precursor hydroxides were precipitated in the aqueous cores of water-in-oil microemulsions and then calcined at 600 degrees C for 2 h to form tin oxide powder. The formation of phase pure tin oxide was confirmed by means of X-ray diffraction analysis. The tin oxide powder was found to be less than 40 nm in particle diameter and to have a higher specific surface area, about 73 m2/g, when compared with tin oxide powder prepared through the conventional precipitation method (19 m2/g).

氧化锡（SnO₂）纳米颗粒是由水、AOT（表面活性剂）和正庚烷（油）组成的油包水微乳液制备而成。前驱体氢氧化物在油包水微乳液的水核中沉淀，然后在600℃下煅烧2小时以形成氧化锡粉末。通过X射线衍射分析证实了纯相氧化锡的形成。与通过传统沉淀法制备的氧化锡粉末（19 m²/g）相比，发现该氧化锡粉末的粒径小于40 nm，比表面积更高，约为73 m²/g。版权所有1999年学术出版社。
