Microwave Dielectric Properties of Ultralow-Temperature Cofirable Ba3V4O13 Ceramics
Ultralow-temperature sinterable Ba3V4O13 ceramics have been prepared through solid-state ceramic route. Structural properties of the ceramic material are studied using powder X-ray diffraction. Ba3V4O13 ceramic has monoclinic structure and the existence of [V4O13](6-) polyhedra is confirmed through Laser Raman studies. The sample sintered at 600 degrees C for 1h shows dense microstructure with microwave dielectric properties of epsilon(r)=9.6, Qxf=56100GHz, and (f)=-42ppm/degrees C. The ceramics under study show good chemical compatibility with aluminum during cofiring.
