dc.description.abstractThe effect of glass addition on sintering temperature and microwave dielectric properties of Cu2ZnNb2O8 (CZN) is investigated for possible low temperature co-fired ceramic (LTCC) application. The CZN ceramic was prepared by the solid-state ceramic route. The phase formation, microstructure and elemental composition of the ceramics were studied using X-Ray Diffraction, Scanning Electron Microscopy, Transmission Electron Microscopy and Energy Dispersive Analysis. The CZN sintered at 975 °C/4 h has ɛr = 15.2, tan δ = 0.0007 (at 5.1 GHz) and τf of −98 ppm °C−1 and CTE = 1.9 ppm °C−1. The addition of LBS and LMZBS glasses lowered the sintering temperature of CZN to below the melting point of silver. The 1 wt% LBS added CZN sintered at 935 °C/4 h had ɛr = 14.7, tan δ = 0.001 (at 5.1 GHz), τf = −19 ppm °C−1 and CTE = −0.6 ppm °C−1. The addition of 0.7 wt% LMZBS to CZN and sintered at 935 °C/4 h had ɛr = 14.8, tan δ = 0.002 (at 5.1 GHz), τf = −39 ppm °C−1 and CTE = −0.9 ppm °C−1en_US
