Abstract
Li2CO3 was added to Ba2V2O 7 ceramics at various contents up to 20 mol% to decrease their sintering time and temperature. The Li2CO3-added Ba 2V2O7 ceramics sintered at 750°C for 2 h had a dense microstructure with a high density. A liquid phase, which existed as an amorphous phase after cooling, was formed during the sintering due to the melting of Li2CO3 and aided the densification of the specimens. The 6.0 mol% Li2CO3-added ceramic sintered at 750°C showed good microwave dielectric properties of εr=10. 93, Q × f=74 513 GHz, and τf=-19.86 ppm/°C, indicating that the Li2CO3-added Ba2V2O 7 ceramic is a good candidate material for low-temperature cofired ceramics.
