Bi2 (Zn 2/3-x/3Nb4/3-2x/3Ti x)O7 ceramics - a low temperature sintered material for LTCC applications

Abstract

Ceramic samples with low sintering temperature were prepared by solid state reaction from the respective high purity oxide powders. Bi2 (Zn 2/3-x/3Nb4/3-2x/3Ti x)O7 were sintered below 900 degree Celcius and the density is above 90%. The frequency dependent dielectric properties of these ceramics up to 1MHz were measured using Agilent 4294A impedance analyser. The dielectric properties of Bi2 (Zn 2/3-x/3Nb4/3-2x/3Ti x)O7ceramics with x = 0 to 0.4 were estimated at microwave frequencies from room temperature to 15 K using Dielectric Post (DP) resonator techniques. The high dielectric permittivity together with the low sintering temperature will make this material an attractive candidate for LTCC applications.
