| titleOfInvention | Barium titanate calcium based leadless piezoelectric ceramic and preparation method thereof |
| abstract | The invention discloses a barium titanate calcium-based lead-free piezoelectric ceramic and a preparation method thereof, wherein the lead-free piezoelectric ceramic has the following general formula: (1-x-y) Ba 0.7 Ca 0.3 TiO 3 —x(Ba 0.95 Li 0.025 Nd 0.025 )TiO 3 —yMHfO 3 -mN; wherein M is at least one of Ba and Ca, and N is CeO 2 、Y 2 O 3 At least one of ZnO and ZnO; x and y are each (Ba) 0.95 Li 0.025 Nd 0.025 )TiO 3 And MHfO 3 Occupying compound (1-x-y) Ba 0.7 Ca 0.3 TiO 3 —x(Ba 0.95 Li 0.025 Nd 0.025 )TiO 3 —yMHfO 3 M represents N in the compound (1-x-y) Ba 0.7 Ca 0.3 TiO 3 —x(Ba 0.95 Li 0.025 Nd 0.025 )TiO 3 —yMHfO 3 In percentage by mass. According to one embodiment of the present disclosure, the lead-free piezoelectric ceramic has excellent piezoelectric performance and simultaneously has lower sintering temperature, and overcomes the defects of the prior art. |
