“…Specimens sintered at 925°C/4 h exhibited a dense microstructure with grain sizes in the ∼8 to ∼11 μm range. The ideal concentration of V 2 O 5 was 1 wt.%, with ε r ∼15.1, Qxf = 91 000 GHz, and τ f ∼ −24 ppm/°C 21 . The Qxf value was influenced by the relative density and the average grain size.…”

The main dielectric properties of several ceramic materials having niobium in their composition, proposed to take part in 5G telecommunication devices, are reviewed. A preliminary basic presentation of 5G systems, the requirements for implementing their use, a concise review of the ceramic compositions containing niobium that have been studied thus far, and an evaluation of their performance are detailed. A survey is presented, including more than 80 different compositions containing niobium, focusing on key parameters, such as dielectric constant, quality factor, temperature coefficient, and sintering temperature. These parameters play a role for assessing the potential application of these ceramics in 5G devices.

“…The microwave dielectric characteristics were studied by the Hakki-Coleman dielectric resonator method in TE011 mode according to the vector network analyzer (HP83752A, USA). The resonance frequency data of the samples were measured at 25 °C and 85 °C, the temperature coefficient of resonant frequency was obtained by the following formula [18]:…”

Li 3 Mg 2 NbO 6 + x wt% Li 2 O-MgO-ZnO-B 2 O 3-SiO 2 (LMZBS, x = 2, 4, 6, 8, 10) microwave dielectric ceramics with the rocksalt structure were primarily investigated by the traditional solid-state method. The microstructures, microwave dielectric properties, and sintering characteristics were studied systematically according to the doping concentration and sintering temperature. It could be seen that the LMZBS glass effectively lower the sintering temperature of Li 3 Mg 2 NbO 6 ceramics from 1250 to 925 °C with microwave dielectric properties changing as a function of the amounts of the LMZBS glass. The experimental results showed that 4 wt% LMZBS glass enabled Li 3 Mg 2 NbO 6 ceramics sintered at 925 °C for 4 h to have excellent microwave dielectric properties: ε r = 16.02, Q × f = 56,455 GHz, τ f = − 18.81 ppm/°C. Therefore, Li 3 Mg 2 NbO 6 ceramics doped with LMZBS glass meet the requirements of low-temperature co-fired ceramics.

“…In particular, adopting low melting‐point additives is the most effective and least expensive method, because the liquid phases during sintering can promote the densification and gain coarsening at low temperature. Therefore, in literature, the dielectric properties of many microwave ceramics have been investigated while different additives such as V 2 O 5 , CuO, LiF, and B 2 O 3 were adopted 31‐41 . Specifically, B 2 O 3 is a widely applied low melting‐point additive to aid sintering 27,37‐41 .…”
