摘要：
Ba(3)Ln(3)Ti(5)Nb(5)O(30) (Ln = La, Nd) ceramics were prepared by the conventional solid-state ceramic route. The sintered samples were characterized by X-ray diffraction and scanning electron microscopy (SEM) methods. They have high dielectric constants, 141 and 203 at 13 MHz for La-based and Nd-based ceramics, respectively. The loss factor of the ceramics increases with frequency. (C) 1998 Chapman & Hall.
