Abstract: |
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. |
