摘要：
A low-firing SrZnV2O7 ceramic was synthesized via a traditional solid-state sintering route. The phase formation, grain morphology, and dielectric performance were studied in detail. Rietveld refinements based on XRD data revealed that SrZnV2O7 crystallized in the monoclinic space group P2(1)/n, which was further confirmed by TEM analysis. The dense SrZnV2O7 ceramic with an epsilon(r) of 11.28, a Qf of 56 660 GHz, and a tau(f) of -27.2 ppm/degrees C was yielded at a low sintering temperature of 740 degrees C for 4 h. Its chemical compatibility with Ag was verified via XRD and SEM-EDS analysis, which rendered SrZnV2O7 a prospective candidate for LTCC technology.
