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 ε_r=10. 93, Q × f=74 513 GHz, and τ_f=-19.86 ppm/°C, indicating that the Li₂CO₃-added Ba₂V₂O ₇ ceramic is a good candidate material for low-temperature cofired ceramics.
