Synthesis of (Ca,Cu)₍₁₋ₓ/₂₎NₓTiO₃ solid solutions (N = Bi, La)

Abstract

Solid solutions (Ca,Cu)₍₁₋ₓ/₂₎NₓTiO₃ (N = Bi, La; x≤0.116) have been synthesized. The effect of bismuth and lanthnum content on the crystal structure parameters and dielectric properties of sintered polycrystal samples has been studied. The heterovalent cationic substitution by trivalent dopants for calcium results in increasing lattice parameters accompanyin the rising x and reduction of the maximun intensity in the temperature dependence of dielectric constant.
