Barium sodium niobate (BNN) glass ceramics were successfully fabricated with controllable crystallization by technology for heating processing and the effects of crystallization temperatures on phase evolution, microstructure, dielectric properties and breakdown strength were investigated systematically. In addition, the empirical power-law dependence of breakdown strength on thickness ($E_b\propto d^{-n}$) was confirmed in BNN glass-ceramic system with an exponent n of 0.21. Based on the results, the BNN glass ceramic crystallized at 800 °C presents a remarkable breakdown strength (BDS) of 2322 kV/cm with the tested thickness of 30 μm, and the highest energy density of 16.6 J/cm³ was achieved.

通过加热处理技术成功地制备了可控结晶的铌酸钡（BNN）玻璃陶瓷，并系统地研究了结晶温度对相演化，微观结构，介电性能和击穿强度的影响。另外，击穿强度与厚度的经验幂律相关性（$E_b\propto d^{--ñ}$在BNN玻璃-陶瓷系统中被证实具有0.21的指数。根据结果​​，在800°C下结晶的BNN玻璃陶瓷具有2322 kV / cm的显着击穿强度（BDS），测试厚度为30μm，并且实现了16.6 J / cm ³的最高能量密度。
