摘要
采用熔融-快冷-可控结晶工艺,制备了(Pb,Sr)Nb_2O_6-NaNbO_3-SiO_2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89ns,具有良好的脉冲平顶和窄的上升沿。在19kV充放电电压、1kHz的充放电频率、4kA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。
Large-sized(Pb,Sr)Nb2 O6-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.
