Generally,　doping　is　an　effective　method　to　improve　the　microwave　dielectric　properties　and　regulate　the　sintering　behavior　of　microwave　dielectric　ceramics.　In　this　study,　the　temperature-stable　Mg1-x(Li0.5Y0.5)xMoxW1-xO4　ceramics　were　prepared　by　a　conventional　solid-state　reaction　method,　and　the　effects　of　doping　on　the　phase,　density,　microstructure,　and　microwave　dielectric　properties　of　the　samples　were　investigated.　The　presence　of　secondary　phase　Li0.5Y0.5MoO4　successfully　improved　the　sintering　behavior　of　the　sample,　achieving　densification　at　low　sintering　temperatures,　while　effectively　adjusting　the　temperature　coefficient　of　resonant　frequency　and　improving　the　temperature　stability　of　the　sample.　Notably,　when　sintered　at　875°C,　Mg1-x(Li0.5Y0.5)xMoxW1-xO4　ceramics　exhibited　satisfactory　microwave　dielectric　properties:　ϵr　=　14.83,　Q×f　=　19,　887　GHz,　and　τf　=　4.11　ppm/ºC,　making　the　ceramics　as　candidates　for　LTCC　technology.　©　Published　under　licence　by　IOP　Publishing　Ltd.
