Microwave dielectric characteristics of tungsten bronze-type Ba4Nd28/3Ti18yGa4y/3O54 ceramics with temperature stable and ultra-low loss

Geng Wang et al.

Summary: Partial substitution of Ga3+ for Ti4+ in BNTG ceramics improved the temperature stability and dielectric loss, mainly influenced by the ionic polarizability. Ultra-low dielectric loss was achieved by controlling grain size, suppressing Ti3+, and impurity phases, leading to excellent dielectric characteristics. Outstanding combination dielectric characteristics were achieved for BNTG microwave ceramics at specific Ga content levels.

Crystal structure, spectra analysis and dielectric characteristics of Ba4M28/3Ti18O54 (M= La, Pr, Nd, and Sm) microwave ceramics

Geng Wang et al.

Summary: High dielectric constant ceramics were synthesized via solid-state reaction, with decreasing rare-earth ion radius leading to lower dielectric constant. The increase in quality factor was associated with higher packing fraction and narrower Raman vibration modes, while negative shift in TCF was related to decreased TiO6 octahedral tilt angle. Infrared reflection spectroscopy indicated dominant infrared vibration modes in microwave dielectric polarization.
