摘要
采用熔融-快冷-可控结晶工艺, 制备了(Pb, Sr)Nb2O6-NaNbO3-SiO2大尺寸玻璃陶瓷, 开展了其介电性能以及脉冲充放电特性研究。实验结果表明: 该玻璃陶瓷材料的介电常数约为340, 具有良好的温度稳定性和正的偏压特性。基于该材料制备的固态脉冲形成线输出脉冲脉宽约为89 ns, 具有良好的脉冲平顶和窄的上升沿。在19 kV充放电电压、1 kHz的充放电频率、4 kA的放电电流条件下, 固态脉冲形成线充放电寿命大于100万次。
Abstract
Large-sized (Pb, Sr)Nb2O6-NaNbO3-SiO2 glass ceramic plate was fabricated via melt-quenching followed by controlled crystallization. Its dielectric properties and charge-discharge properties were investigated. The results show that the dielectric constant is about 340 and has good temperature and voltage stability. The output pulse width of glass-ceramic pulse forming line is about 89 ns, and shows good flatness and steep front edge. The charge-discharge lifetime of pulse forming line is larger than one million times under the charge voltage of 19 kV, discharge current of 4 kA and operating frequency of 1 kHz.
