Abstract
This paper uses solid state sintered technology to prepare leadless piezoceramics K0.5Na0.52Nb1-xSbxO3, where level of doping x values respectively 0, 0.02, 0.03, 0.04, 0.05, 0.06 and perform measurement of relevant performance and constant.Through relevant test and measurement, it is not hard to conclude: when firing temperature is 1140℃, level of doping x is 0.02, the piezoceramic modulus of sample d33 is 111pC/N, value of permittivity εr is 1200, mechanical quality factor Qm is 10, electro-mechanical coupling factor kp is 0.387, dielectric losses tanδ is 0.11, which means that it is successful to develop piezoceramics with excellent piezoelectric property and ferroelectricity.关键词
