摘要：

In this study, 0.8 KNbO3 (KN) -0.2 BaTiO3 (BT) ceramics were prepared using KN powder with the diameter of 100 nm and BT powders with the diameter of 100, 300, or 500 nm. The relative densities were more than 96 % of the theoretical densities of the samples. The dielectric constant of the samples was temperature-stable at temperatures between -50 and 300 degrees C and it was found that the dielectric constant of the 0.8KN-0.2BT ceramics increased as the BT diameter increased.
