摘要

This article presents the effect of lead-borosilicate glass (65PbO-20B(2)O(3)-15SiO(2), mol%) (PBS) addition on the structure, microstructure, dielectric, ferroelectric and energy storage properties of Ba0.9995La0.0005TiO3 (BLT) ceramics system has been systematically investigated. XRD analysis revealed the tetragonal (T) phase at room temperature. Addition of PBS glass results in decrease in ferroelectricity and improved breakdown properties. High maximum polarization (P-s similar to 21.53 mu C/cm(2)) and remnant polarization values (2P(r)similar to 8.75 mu C/cm(2)) were obtained from ferroelectric (P-E) hysteresis loops for the BLT ceramics. Two dielectric anomalies at 420 K and 600 K were observed due to the phase transformation. The glass-ceramics heat treated at 900 degrees C for 3 h was found to possess optimal properties with break-down strength of >300 kV/cm and energy storage density of 0.564 J/cm(3), which is a promising glass-ceramic ferroelectric capacitor material for high energy storage density dielectrics.
