Abstract: One variation of a contact material includes: a base material including a first amount of Lanthanum, a second amount of Nickel, and a third amount of Oxygen; a fourth amount of a first doping agent configured to stabilize a crystal structure of the base material; and a fifth amount of a second doping agent, in the set of doping agents, configured to limit thermal expansion of the base material. The contact material exhibits: a thermal expansion coefficient between 10.0×10?6K?1 and 15.0×10?6K?1 at temperatures between 25 degrees Celsius and 1100 degrees Celsius; and an electrical conductivity greater than 200 Siemens-per-centimeter at temperatures within a temperature range of 700 degrees Celsius to 1300 degrees Celsius.
