Abstract:
( K 0.5 Bi 0.5 ) 0.4 Ba 0.6 Ti O 3 nanowires have been fabricated by a sol-gel–hydrothermal method at 200°C. X-ray diffraction result shows that the nanowires have a tetragonal perovskite structure. Transmission electron microscopy investigations exhibit that the as-prepared nanowires are single crystalline grains with diameters of about 40nm and lengths reaching up to 800nm. The (K0.5Bi0.5)0.4Ba0.6TiO3 ceramics with a relative density of 97% can be fabricated from the high quality nanowires even by a conventional sintering process, which showed that typical characteristics of relaxor ferroelectrics, the indicator of degree of diffuseness γ and Curie temperature TC (100kHz), were 1.65 and 220°C, respectively.
