A new BiVO4/Li0.5Sm0.5WO4 ultra-low firing high-k microwave dielectric ceramic
Source abstract
Abstract
Dense ceramic samples in the (1−x) BiVO4−xLi0.5Sm0.5WO4 (0.05 ≤ x ≤ 0.1) system are prepared using the solid-state reaction process. A single solid–solution phase with monoclinic structure formed through the entire compositions and the unit cell volume increases linearly with x. When x = 0.07, the composition of 0.93BiVO4–0.07 Li0.5Sm0.5WO4 readily sintered at 750 °C has excellent microwave properties with a high permittivity of 73.9, and a Q × f value of 9054 GHz and a near-zero temperature coefficient of −1.61 ppm/°C. The ceramics have applications for microwave devices requiring ultra-low sintering temperatures.
