摘　　要：纳米钛酸钡具有介电常数高、损耗低,其优良的铁电、压电和绝缘性能,被用于制造陶瓷敏感元件、多层陶瓷电容器、记忆材料等。最近几年,纳米BaTiO3粉体的制备及其形貌控制技术得到了很大发展。综述了钛酸钡粉体的溶胶凝胶合成技术,并提出了其发展方向。Barium titanate powder has higher permittivity, lower dielectric loss, good ferroelectric, piezoelectricity and electric insulation properties. Barium titanate is a type of ceramic material widely used in electronics industry for fabrication of multilayer ceramic capacitors, memory materials, and so on. Preparation and control morphology of barium titanate nano-particles were greatly developed. The sol-gel preparation of barium titanate is reviewed. The future trends are also prospected.
