“…In general, most of the tantalates possess high quality factors but need high sintering temperatures to densify [7,[31][32][33][34][35]. In contrast, vanadates usually have lower densification temperatures but inferior quality factors and temperature stability of the resonance frequency [27,[36][37][38][39][40][41][42][43]. Compared with these ceramics, the sintering temperature of BaTa 2-x V 2?x O 11 (0.1 B x B 0.6) is distinctly decreased and the temperature stability of resonance frequency is significantly improved.…”

Compositional modification engineering was designed to simultaneously reduce the sintering temperature and improve the dielectric properties of BaTa 2 V 2 O 11 via insitu adjusting the V 5? /Ta 5? molar ratio. A series of BaTa 2-x V 2?x O 11 ceramics, fabricated by a solid-state reaction method, were characterized for structural evolution and dielectric properties variations. In-situ adjusting V 5? /Ta 5? molar ratio significantly lowered the sintering temperature of BaTa 2 V 2 O 11 and prominently improved the temperature stability of resonance frequency which is explained by the dielectric dilution theory. Competitive microwave dielectric properties with e r = 11.5-25.9, Q 9 f = 22,172-42,660 GHz, and s f = 42.4-74.6 ppm/8C were achieved in the BaTa 2x V 2?x O 11 ceramics sintered at 620-840 oC. All the results indicate that the molar ratio of V 5? is primarily responsible for improving the densification behavior and dielectric characteristics of BaTa 2-x V 2?x O 11 , which in turn increases the appropriateness in further practical applications.

“…have been investigated for LTCC applications. However, several attempts have been also made to identify new vanadium based compounds, including BaV 2 O 6 , SrV 2 O 6 , LiMgVO 4 , etc. with ultra‐low firing temperature which makes them suitable candidates for ULTCC applications.…”

In this study, the (Ca0.95M0.05)V2O6 (M = Zn, Ba) and the CaV2O6 ceramics were synthesized through a solid‐state reaction method, and the effects of Zn2+ and Ba2+ substitution on the structure, sintering temperature, densification, microstructure and microwave dielectric properties of CaV2O6 ceramic were analysed. The XRD patterns of the sintered samples indicated a single‐phase of CaV2O6 in all temperatures. Substitution of Zn2+ caused a lower sintering temperature and improved the densification of the CaV2O6 ceramic. While the dielectric properties of the (Ca0.95Ba0.05)V2O6 compound were not desirable, the (Ca0.95Zn0.05)V2O6 sample sintered at 650°C for 4 hours showed significant dielectric properties, with εr = 10.29, Q × f ~ 53 000 GHz (at 15.5 GHz) and τf = −72.37 ppm/°C. Moreover, the chemical compatibility of the CaV2O6 ceramic with Al electrode was examined.
