Demonstrates the fabrication of low-temperature co-fired ceramics, optimizing properties for dielectric applications, indicating effective material control.
Key Points
The aim is to fabricate temperature-stable, glass-free low-temperature co-fired ceramics with optimal microwave dielectric properties.
Reactive liquid-phase sintering of mixtures at 850 °C
Systematic adjustment of Li2WO4 content to tailor properties
Chemical compatibility tests with Ag electrodes
Sintered ceramics achieved high relative densities of 94–98%
Temperature coefficient of resonant frequency τf shifted from +23.97 to -45.48 ppm/°C with increased Li2WO4
Optimal dielectric properties at x = 0.5: εr = 9.19, Q × f = 45,900 GHz, τf = -1.15 ppm/°C
