The effect of the dopants Ti, V, Cr. Mn, Ni, Ho, Er, Tm deliberately introduced into the melt of Czochralski grown lithium niobate (LiNbO 3 ) crystals on their electrophysical properties — electric conductivity, dielectric permittivity and loss tangent — has been studied. The characteristics were measured at temperatures up to 1200°C. The mechanism of dopant introduction into the crystalline lattice and the nature of electric conductivity of LiNbO 3 at varius temperatures are discussed.
