Relations on synthesis, crystal structure and microwave dielectric properties of SrZnP2O7 ceramics

Different experimental conditions were applied to investigate the optimum sintering properties of SrZnP2O7 ceramics, and its crystal structure and microstructure were investigated by X-ray powder diffraction and scanning electron microscope, respectively. The microwave dielectric properties were measured using a network analyzer. In calcination process, SrZnP2O7 powders were synthesized at different temperatures. The sintering characterizations and electric properties of the SrZnP2O7 ceramics prepared from the different calcined SrZnP2O7 powders were studied systematically. Better microwave dielectric properties can be obtained when using well calcined powders and optimum sintering conditions.
