摘要：

Lead-free ceramic with the composition of Bi1.34Fe0.66Nb1.34O6.35 was prepared by a solid state reaction method. The phase structure, microstructure and dielectric performances of Bi1.34Fe0.66Nb1.34O6.35 ceramic were systematically investigated. X-ray diffraction pattern showed that the ceramic has a cubic pyrochlore structure with a unit cell parameter of a = 10.4998 a"<<. When the sintering temperature was 1000 A degrees C, the ceramic possessed excellent dielectric performance with high relative permittivity of similar to 165 and low dielectric loss of similar to 1 %. Furthermore, Bi1.34Fe0.66Nb1.34O6.35 ceramic exhibits a near-zero temperature coefficient of similar to+21 ppm/A degrees C, which indicates that this ceramic is a promising candidate for thermally stable devices.
