Microwave dielectric properties of MgCo2(VO4)2 ceramics synthesized by a sol–gel method

MgCo2(VO4)2 (MCV) ceramics have been prepared by a sol–gel method as potential candidates for use in microwave applications as a low-temperature co-fired ceramic (LTCC). The sintering and microwave dielectric properties of sol–gel processed MCV were compared with those of solid-state reaction processed MCV. The results showed that sol–gel processed MCV had a higher sinterability due to its much finer particle size. The sol–gel processed MCV was also found to have superior microwave dielectric properties compared with solid-state reaction processed MCV especially at low sintering temperatures.
