Abstract
In this study, we selected an appropriate crystallization temperature (750 °C) to obtain glass-ceramics with the excellent hardness and energy storage properties. Besides, increasing the dielectric breakdown strength (DBS) increases along with the crystallization temperature was owing to the dense microstructure. Consequently, the good energy properties, including a high energy efficiency of 89.79% with a high recoverable energy density of 1.74 J/cm3can be achieved in the sample crystallized at 750 °C for 2 h. More significantly, the corresponding hardness of the energy storage glass-ceramics has not been reported before. These results demonstrate that the prepared sample has promise use in the dielectric capacitors field.
