Wpływ składu procentowego na własności elektryczne roztworu stałego Pb/Zr[x]Ti[1-x]/O[3] dla 0,46 ≤ x ≤ 0,60

Abstract

Temperature depedence of dielectric constant ε, electric conductivity, Seebeck's coefficient, were studied around the morphotropic boundary of the solution. On the ground of polaron theory of transport, charge carrier concentration n and mobility were calculated with the use experimental data on electric conductivity and Seebeck's coefficient reported here. The results show a depedence of the electrical parameters /(ε, δ, α, n, μ) on the composition of the Pb/Zr[x]Ti[1- x]/O[3] solution and clear evidence of their anomalies at the morphotropic boundary (x ≈ 0.53) separating the tetragonal phase from rhomboedric.
