Crystallization kinetics behavior and dielectric energy storage properties of strontium potassium niobate glass-ceramics with different nucleating agents
Source abstract
Abstract
Abstract A series of strontium potassium niobate (KSN-based) glass-ceramics with different nucleating agents have been prepared by conventional controlled crystallization method. The effects of different nucleating agents on crystallization kinetics behavior, dielectric properties and energy storage performances of glass-ceramics have been investigated. It was found that nucleating agents can improve the reaction rate constant (k) of crystallization, which made the KSN-based glasses crystallize at low temperature. Due to the increase of crystallinity, the dielectric constant rose and the breakdown strength decreased. The maximum theoretical energy storage density of 13.5 J/cm 3 was obtained when 3 mol.% CaF 2 were added as nucleating agents.
