Abstract
K0.5Bi0.5TiO3 (KBT) nanowires have been successfully synthesized by a simple hydrothermal method in KOH solution, which acts as a mineralizer in the hydrothermal process. The KBT nanowires were characterized by X-ray diffraction (XRD) and transmission electron microscope (TEM). The results show that KBT nanowires with tetragonal phase have width of 5 nm and length of 200 nm. The as-prepared nanowires were employed to fabricate KBT ceramic by sintering at 1060 °C. The specimen exhibits ɛr of 710 and tan δ of 0.043 under room temperature at 1 kHz. It was found that the KBT ceramics present typical characteristics of relaxor ferroelectrics.
