摘　　要：采用压坯后的玻璃粉与球头座烧结,烧结产物作为密封体用来生产快速响应裸露感温点低温、高压热敏电阻温度传感器,通过扫描电子显微镜(SEM)分析玻璃烧结体的形貌,利用国防计量标准测量传感器的精度,振动台和高压气源分别测试传感器的耐振性和气密性,最终确定最佳烧结工艺参数。Glass dust which was impacted with ball were sintered. The sintering product as airproof parts was used to produce thermistor which can response quickly and used in the condition of low temperature and high pressure. SEM analysed the morphology of airproof parts, and national defence measurement standard measured the precision. The vibration strength and air tightness of thermistor were measured by shaking table and high pressure gas. Finally made certain the parameters of technics.
