Effect of lowering the sintering temperature in Mg4Nb2O9 microwave ceramic by doping LMBS glass
Low-temperature co-fired ceramics (LTCC) with excellent microwave dielectric properties have been extensively studied recently due to the increasing demand for miniaturizing microwave devices and reducing the size of wireless communication systems. The Mg4Nb2O9 ceramic, known for its low dielectric loss, is suitable for applications in 5G/6G technology. This research focuses on lowering the sintering temperature of Mg4Nb2O9 ceramic to meet LTCC technology requirements. The results indicate that the Li2O–MgO–B2O3–SO2 (LMBS) glass demonstrates good wetting behavior and reduces the sintering temperature of Mg4Nb2O9 ceramic from 1350 °C to 950 °C. The phase composition, microstructures, densities, and microwave dielectric properties of Mg4Nb2O9 + x wt% LMBS glass (x = 0, 3, 4, 5, 6) samples are further investigated. Ultimately, the Mg4Nb2O9 + 5 wt% LMBS glass sample exhibits microwave dielectric properties with ɛr = 12.16, Q × f = 45,273 GHz, and τf = −75.3 ppm/°C.
期刊介绍：
The Journal of Materials Science: Materials in Electronics is an established refereed companion to the Journal of Materials Science. It publishes papers on materials and their applications in modern electronics, covering the ground between fundamental science, such as semiconductor physics, and work concerned specifically with applications. It explores the growth and preparation of new materials, as well as their processing, fabrication, bonding and encapsulation, together with the reliability, failure analysis, quality assurance and characterization related to the whole range of applications in electronics. The Journal presents papers in newly developing fields such as low dimensional structures and devices, optoelectronics including III-V compounds, glasses and linear/non-linear crystal materials and lasers, high Tc superconductors, conducting polymers, thick film materials and new contact technologies, as well as the established electronics device and circuit materials.
