The paper is concerned with the determination of the set of all possible effective conductivities of a two-phase anisotropic material. A family of conductivity tensors with respect to a mixture of the two phases is defined, its macroscopic behaviour is investigated with the aid of H- convergence theory. The complete characterization of all effective tensors regarding the two phase-associated ones is shown to depend on the relative magnitudes of their eigenvalues.
