Cermets with four different compositions of lanthanum and cerium oxide in Cu-Ni-Ag alloy as metallic matrix were fabricated by powder metallurgy and characterized by their structural and physical properties. It was detected the formation of intermetallic compounds as a consequence of diffusion processes. The powder metallurgy allowed to obtain samples with high electrical conductivities and interesting structural characteristics with potential technological applications.
