摘　　要：金属陶瓷焊接是钠硫电池最重要的工艺环节之一。为了提高钠硫电池的安全性,通过真空热压技术研究了温度、真空度、压力等对金属陶瓷焊接件氦漏率与强度的影响。研究结果表明,在真空度为10^(-2)Pa、温度为530℃、压力为15MPa的条件下,可以得到氦漏率为10^(-8) Pa·m^3·s^(-1),强度在1MPa以上的金属陶瓷焊接件。Cement-welding is one of the most important aspects for processing of sodium sulfur battery. In order to improve the safety of the sodium-sulfur battery, vacuum thermocompression technology was adopted to explore the impact of temperature, vacuum and pressure to the helium leak rate and intensity of cement-welding pieces. The results show that when vacuum is of 10 ^-2 Pa, temperature is of 530 ℃ and the pressure is of 15 MPa, it is available to obtain cement-welding pieces with a helium leak rate of 10 ^-8Pa· m3· s^-1 and more than 1 MPa strength.
