中文摘要：
钛酸钡是一种性能优异的电子陶瓷材料．作为一种典型的铁电和介电材料，钛酸钡在制作非线性电子元件、介电放大器、热变电阻器、多层陶瓷电容器（MLCC）、动态随机存取存储器（DRAM）和其它光电器件方面有着广泛的应用．虽然许多溶液方法如共沉淀法、溶胶．凝胶法、水热法、喷雾高温分解法等已被用于制备符合化学计量的微米或纳米级的钛酸钡颗粒，但制备棒状纳米钛酸钡的文献报道还较少，且未见用反相微乳液法合成钛酸钡纳米棒的报道．
英文摘要：
BaTiO3 nanorods were synthesized in water/OP-10/n-hexanol/cyclohexane quaternary reverse microemulsion solution at 60 ℃. The effects of the molar ratio of water to surfactant and the concentration of reactants on the diameters and lengths of BaTiO3 nanorods were studied. The products were characterized by TEM, XRD and ICP. The results show that the diameters and lengths of the prepared BaTiO3 nanorods with a cubic phase and a single crystal are approximately 15-80 nm and 300-3 900 nm, respectively. And the molar ratio of barium to titanium of products is 1.0.
