Multilayer ceramic capacitors (MLCCs) demonstrate considerable potential for advance pulsed power systems, owing to their high-power density and fast charge/discharge capabilities. In light of the increasing demand energy conservation, minimizing dissipation in storage while maintaining high recoverable densities is essential practical application. this study, building upon morphotropic phase boundary (MPB) between Bi0.5Na0.5TiO3 (BNT) NaNbO3, heterogeneous cations (Ba2+, Zn2+, Nb5+) are...
Abstract Rare earth tri‐doped precursor glasses (PGs) were prepared by traditional high‐temperature melting method, and NaSr 2 Nb 5 O 15 transparent glass–ceramic (GC) was obtained subsequent heat treatment. Results exhibit that the up‐conversion emission intensity of GC is greatly enhanced compared to PG. Benefiting from multiple bands Ho 3+ Tm their different temperature dependence, multi‐ratio optical measurement realized. The ultimate relative sensitivity ( S r ‐max ) can reach 2.00% K...
Developing dielectric capacitors with both excellent recoverable energy storage density (Wrec) and high breakdown strength (DBS) are highly desired for pulsed power electronic systems. Although glass ceramics known to potentially possess simultaneously a DBS relatively constant (εr), it is still long-standing challenge obtain performance in ceramics. In this work, based on the consideration of electronegativity its effects degree polymerization, SnO2 addictive was introduced reconstitute...
Abstract Glass–ceramics capacitors have great application potential in pulsed power systems, due to ultrafast discharge speed and high dielectric breakdown strength (BDS). Here, lead‐free niobate glass–ceramic materials were synthesized, the effects of heat treatment temperature on dielectric, ferroelectric, energy storage properties glass–ceramics investigated comprehensively. The results exhibit that permittivity first increases then decreases as crystallinity increases; however, BDS...
