The NaKNbO3-B2O3-SiO2 glass ceramic materials prepared by using high temperature melting and controlled crystallization were studied in this study. As studied for the microstructure, crystallization power, the conductivity matching degree of glass phase and crystal phase, and the effect of interface on ferroelectric and dielectric performance, high energy storage density can be possessed to solve interfacial polarization caused by the difference between the two phases on performance, distribution and content for glass ceramic material observed for morphology and content between glass phase and crystal phase by DSC, XRD, Raman, FT-IR, SEM/TEM, which is illustrated from thermal shock polarization current, complex impedance spectrum, hysteresis loop analysis measured. Studied by effect of composition, structure and interface polarization on material energy storage performance, the internal relation between microstructure and interface polarization and macroscopic energy storage is established to provide theoretical basis for the design of high energy storage density high voltage capacitor and pulse power supply, which can reveal the mechanism of interfacial polarization of composite dielectric materials.
