Sintering Behavior and Microwave Dielectric Properties of Low-Permittivity SrMgSi2O6 Ceramic
Low-permittivity SrMgSi 2 O 6 microwave dielectric ceramics were synthesized via a conventional solid-state reaction method. Further, their sintering behavior as well as structural and microwave dielectric properties were studied. The x-ray diffraction patterns of the SrMgSi 2 O 6 and Sr 2 MgSi 2 O...
