Abstract: Highlights: [•] Highly textured Ca9Co12O28 ceramics have been prepared by hot pressing method. [•] TE properties of the samples show bidimensional anisotropic character. [•] Lattice thermal conductivity is the main thermal transference in the samples. [•] At 600°C the samples have a ZT =0.18 in the direction perpendicular to the hot pressing direction.
