| 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. |
