| Abstract: | The electric properties of Pb(Li 1/4 Nb 3/4 )O 3 Pb(Fe 1/3 Sb 2/3 ) PbTiO 3 PbZrO 3 quadruple ceramics with different proportions and dopants are investigated by analyzing piezoelectric properties, mechanic quality and the diffusive graph of relative dielectric constant vs temperature of different samples. It is found that the samples exhibit high piezoelectric constant, up to 340×10 -12 C/N, and the diffusive temperature dependence of dielectric properties. To improve the properties, the techniques for preparation and test are also investigated. (9 refs.) |
