Research on Lithium Niobate Piezoelectric Ceramics by Vacuum Hot-Pressing Sintering AITranslate
Abstract AITranslate
Lithium niobate(LN) powder was sintered by vacuum hot-pressing sintering to prepare LN piezoelectric ceramics,with the optimal sintering parameters determined by changing the sintering temperature and holding time.The density,microstructure,phase composition,piezoelectric and dielectric properties of the sintered samples were tested.The results show that LN piezoelectric ceramics prepared under the conditions of a sintering temperature of 900 °C,a holding time of 120 minutes,and a pressure of 35 MPa exhibit the highest density(4.62 g/cm3) and the maximum piezoelectric constant d33(8.7 pC/N).Compared with the methods of traditional solid-phase sintering and CO2 laser sintering,the piezoelectric constant of the prepared LN piezoelectric ceramics increases by 7.9 pC/N and 2.7 pC/N,respectively.When the test frequency is within 1 kHz~1 MHz,the dieletric constant of LN piezoelectric ceramics prepared under different conditions decreases rapidly and then tends to stabilize.
