  • Sandwich-structured dielectric materials for pulse energy storage as well as preparation method and application thereof
    Patent number: 11735360
    Abstract: A sandwich-structured dielectric material for pulse energy storage is provided as well as a preparation method thereof. Employing a sandwich structure and combining the properties of ceramic-glass materials prepares a high performance dielectric material for pulse energy storage, in which the ceramic dielectric is core-shell structured powder of BaxSr1-xTiO3 coated with SiO2, and the glass material is alkali-free glass AF45, of which the chemical composition is 63% SiO2-12% BaO-16% B2O3-9% Al2O3. AF45 alkali-free glass paste is spin-coated on both sides of the ceramic and calcined to get a layer-structured material of glass-ceramic-glass.
