- Abstract:
- 0.02Pb(Sb0.5Nb0.5)O3-0.98Pb1-2xBaxSrx(Zr0.53Ti0.47)O3 piezoelectric ceramics (where x=0.02,0.03,0.04,0.05) were prepared by traditional solid-state sintering method. The different The effect of Ba, Sr composite doping amount and sintering temperature on the structure and electrical properties of ceramics. The results show that when x = 0.04 and the sintering temperature is 1260 ℃, the performance of piezoelectric ceramics is the best, where d33 = 615 pC/N, ε33/ε0=2224, tanδ=2.11%; then install the ceramic chip of this formula into the sensor, test its charge sensitivity, maximum lateral sensitivity ratio and maximum linearity error, the charge sensitivity is 2.72 pC/(m s-2) , the maximum lateral sensitivity ratio is less than 5%, and the maximum linear error is 2.97%, which meets the requirements for the use of general vibration test type sensors.
