N2 - The structural stability and microstructure of (1-x)Ba(Mg1/2W1/2)O3-xBa(RE2/3W1/3)O3 (RE=Sm, Dy, Y, Yb) ceramics have been investigated by X-ray diffraction (XRD), Raman spectrometry, transmission electron microscopy (TEM) and scanning electron microscopy (SEM) in this work. Microwave dielectric properties were studied in the frequency range 7-13GHz. Phase-pure solid solutions formed in space group Fm-3m within the compositional range of x=0.01-0.05. The local ordering of the two cations (RE3+ and W6+or Mg2+) produced an internal lattice-induced strain and charge-imbalance clusters which greatly affected the structural stability and Q×f value.
