Abstract
Abstract A low‐firing SrZnV 2 O 7 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 SrZnV 2 O 7 crystallized in the monoclinic space group P2 1 /n, which was further confirmed by TEM analysis. The dense SrZnV 2 O 7 ceramic with an ε r of 11.28, a Qf of 56 660 GHz, and a τ f of −27.2 ppm/°C was yielded at a low sintering temperature of 740°C for 4 h. Its chemical compatibility with Ag was verified via XRD and SEM‐EDS analysis, which rendered SrZnV 2 O 7 a prospective candidate for LTCC technology.
