Microwave Dielectric Properties of Ultralow‐Temperature Cofirable Ba₃V₄O₁₃ Ceramics

Abstract

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°C for 1 h shows dense microstructure with microwave dielectric properties of εr = 9.6, Q × f = 56 100 GHz, and τf = −42 ppm/°C. The ceramics under study show good chemical compatibility with aluminum during cofiring.

Structure and Microwave Dielectric Properties of Ultralow‐Temperature Cofirable BaV2O6 Ceramics

“…Recently we have reported the microwave dielectric properties of Ba 3 V 4 O 13 ceramic in the BaO-V 2 O 5 binary system, which can be well sintered at 600°C with ε r = 9.6, Qxf = 56100 GHz, and τ f = -42 ppm/°C. [28] However, the microwave dielectric properties of BaV 2 O 6 have not yet been investigated. In the present work, we prepared BaV 2 O 6 ceramics and studied their microwave dielectric properties and chemical compatibility with Al electrodes to evaluate their potential to be used as materials for ULTCC technology.…”

Effect of a minute substitution on the structure and microwave dielectric properties of novel LiCoVO4 ceramics for ULTCC applications

“…For instance, Mg 3 (VO 4 ) 2 , Ba 3 (VO 4 ) 2 , MgZn 2 (VO 4 ) 2 , and BaMg 2 (VO 4 ) 2 ceramics all revealed a good combination of microwave dielectric properties with a sintering temperature <960°C. BaV 2 O 6 and Ba 3 V 4 O 13 , belonging to the BaO-V 2 O 5 family, were reported to be good candidates for ULTCC applications [23,24]. The R 2 V 2 O 7 (R = Ba, Sr and Ca), BaO-MO-V 2 O 5 (M = Mg, Zn), and SrMV 2 O 7 (M = Mg, Zn) families have also been found to offer good microwave dielectric properties at ultra-low sintering temperatures [25,26].…”

Ultra-low temperature sintering and temperature stable microwave dielectrics of (Mg1-xZnx)V2O6 (x= 0–0.09) Ceramics

“…A number of V 2 O 5 -based ceramic families have been studied and reported for LTCC applications over the last decade. For instance, BaV 2 O 6 and Ba 3 V 4 O 13 , belonging to the BaO-V 2 O 5 family, have been reported to be good candidates for ULTCC applications [6,7]. The R 2 V 2 O 7 (R = Ba, Sr and Ca), BaO-MO-V 2 O 5 (M = Mg, Zn), and SrMV 2 O 7 (M = Mg, Zn) families have also been found to offer good microwave dielectric properties at ultra-low sintering temperatures [8,9].…”
