摘要：
This paper presents structural and electrical data on the delafossite compound CuNi0.5Ti0.5O2, Ceramics of CuNi0.5Ti0.5O2 Were prepared via solid state synthesis techniques in a controlled atmosphere of pO(2) = 10(-3) atm. The compound crystallized into the 3R delafossite phase with hexagonal lattice parameters of a = 3.0079 (+/- 0.0004) angstrom and c = 17.2543 (+/- 0.003) angstrom. The electrical properties of the material are characterized by a room temperature conductivity of 2 x 10(-6) S/cm. The conductivity exhibits an Arrhenius-like temperature dependence with an activation energy of 0.48 eV. (C) 2005 Elsevier B.V. All rights reserved.
