Abstract:
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
