Abstract
Lead-free piezoelectric ceramics 0.95 (K0.5 Na0.5 )NbO3 -0.05CaZrO3 were prepared by traditional ceramics process.The effect of the sintering temperature and poling conditions on piezoelectric properties of 0.95(K0.5 Na0.5 )NbO3-0.05CaZrO3 ceramics was investigated.Results show that the optimum sintering temperature of 0.95(K0.5 Na0.5 )NbO3-0.05CaZrO3 ceramics is 1 170℃.Piezoelectric properties of 0.95(K0.5 Na0.5 )NbO3-0.05CaZrO3 ceramics under the opti-mum sintering temperature are piezoelectric constant d33 of 210 pC/N,planar electromechanical coupling factor kp of 0.40. At the same time,the results show that the optimum poling condition for 0.95(K0.5 Na0.5 )NbO3-0.05CaZrO3 ceramics is poling electric field of 4 kV/mm and poling temperature of 70℃.关键词
