Abstract:	SrLa2Mg2W2O12 and Sr2La2MgW2O12 ceramics were prepared by the conventional solid-state ceramic route and their dielectric properties were investigated in the radio and microwave frequency regions. SrLa2Mg2W2O12 sintered at 1500 degrees C has epsilon(r)=25.2, Q(u) x f=15 900 GHz (at 4.9 GHz), and tau(f)=0 ppm/degrees C. Sr2La2MgW2O12 sintered at 1525 degrees C has epsilon(r)=24.7, Q(u) x f=35 000 GHz (at 4.7 GHz), and tau(f)=-83 ppm/degrees C. The dielectric properties of these ceramics are reported for the first time.
