Microwave dielectric properties of low temperature firing (Li1/2Nd1/2)WO4 ceramic

A new kind of low temperature sintering ceramic with composition of (Li1/2Nd1/2)WO4 were prepared by solid state reaction method. The phase and structure of the ceramics were characterized by X-ray diffraction (XRD), scanning electron microscopy. The microwave dielectric properties of the ceramics were studied using a network analyzer. All the XRD patterns can be fully indexed as single-phase tetragonal structure (I41/n), with lattice parameters a = b = 5.25789 and c = 11.39124 . The ceramic sintered at 775 A degrees C for 4 h exhibits a good microwave dielectric properties with permittivity about 16.1, Q x f about 4,210 GHz and TCF about 142 ppm/A degrees C.
