Ultralow‐temperature sinterable Ba 3 V 4 O 13 ceramics have been prepared through solid‐state ceramic route. Structural properties of the ceramic material are studied using powder X‐ray diffraction. Ba 3 V 4 O 13 ceramic has monoclinic structure and the existence of [V 4 O 13 ] 6− polyhedra is confirmed through Laser Raman studies. The sample sintered at 600°C for 1 h shows dense microstructure with microwave dielectric properties of ε r = 9.6, Q × f = 56 100 GHz, and τ f = −42 ppm/°C. The ceramics under study show good chemical compatibility with aluminum during cofiring.
