摘要

:钛酸钡(batio3, BT)由于其优异的介电、铁电、压电和绝缘性能,被广泛应用于多层陶瓷电容器、超级电容器、热敏电阻、铁电器件和压电器件等电子元件的制造。BT基组件的性能高度依赖于BT纳米颗粒的质量。传统固相法合成的BT纳米颗粒存在粒径大、分布不均匀等缺点,而液相法克服了这些缺点,具有纯度高、组成均匀、粒径小的特点,是目前制备BT纳米颗粒的主要方法。本文介绍了BT纳米颗粒的各种液相制备方法,比较了各种方法的优缺点,总结了影响BT纳米颗粒结晶质量的优化工艺参数,从而获得结晶质量高、粒径小、分布均匀的BT纳米颗粒。

Liquid-phase preparation of BaTiO3 nanoparticles

Barium titanate (BaTiO3, BT) is widely used in the manufacture of electronic components such as multilayer ceramic capacitors, supercapacitors, thermistors, ferroelectric devices and piezoelectric devices due to its excellent dielectric, ferroelectric, piezoelectric and insulating properties. The performance of BT-based components is highly dependent on the quality of the BT nanoparticles. Large particle size and uneven distribution are the disadvantages of the BT nanoparticles synthesised by the traditional solid-phase reaction, however, the liquid-phase method can overcome these shortcomings, which has the characteristics of high purity and uniform composition with small particle size, and therefore is the main method for the preparation of BT nanoparticles. This review described various liquid-phase preparation methods of BT nanoparticles and compared the advantages and disadvantages of these methods, thereafter the optimised process parameters that affected the BT crystalline quality were summarised so as to obtain BT nanoparticles with a high crystalline quality, small particle size and even distribution.
