A newly designed glass-ceramic system consisting of 15Bi₂O₃-15Nb₂O₅-40SiO₂-30Al₂O₃ was successfully prepared, which was followed by its controlled crystallization at different heating temperatures. The effects of crystallization temperature on the microstructure, phase evolution and the energy storage behaviors of the novel material were systematically investigated. A maximum theoretical energy storage density of up to 15.3 J/cm³ was found in the samples heated at 800 °C. The polarization-electric (PE) hysteresis loops of this material exhibited very good linear character and high energy efficiency. In addition, an approximate value of 25 ns for discharged period T has been obtained, which demonstrated that most of the energy stored in dielectric was released over a very short time. The maximum powder density exceeds a high value of 90 MW/cc in a 390 kV/cm electric field. Therefore, the new developed Bi₂O₃-Nb₂O₅-SiO₂-Al₂O₃ glass-ceramic can be used as an alternative, promising high-performance electrostatic capacitor material.

成功制备了由15Bi ₂ O ₃ -15Nb ₂ O ₅ -40SiO ₂ -30Al ₂ O ₃组成的新设计的玻璃-陶瓷体系，随后在不同的加热温度下进行了可控的结晶。系统地研究了结晶温度对新型材料的微观结构，相演化和储能性能的影响。最大理论储能密度高达15.3 J / cm ³在加热到800°C的样品中发现了。这种材料的极化电（PE）磁滞回线表现出非常好的线性特性和高能效。另外，对于放电周期T，获得了大约25 ns的值，这表明存储在电介质中的大部分能量是在很短的时间内释放的。在390 kV / cm的电场中，最大粉末密度超过90 MW / cc的高值。因此，可以将新开发的Bi ₂ O ₃ -Nb ₂ O ₅ -SiO ₂ -Al ₂ O ₃玻璃陶瓷用作替代品，有望成为高性能的静电电容材料。
