CERMET ANODE COMPOSITIONS WITH HIGH CONTENT ALLOY PHASE

摘要

Cermet electrode compositions comprising NiO-NiFe2O4-Cu-Ni, and methods for making, are disclosed. Addition of nickel metal prior to formation and densification of a base mixture into the cermet allows for an increase in the total amount of copper and nickel that can be contained in the NiO-NiFe2O4 oxide system. Nickel is present in a base mixture weight concentration of from 0.1% to 10%. Copper is present in the alloy phase in a weight concentration of from 10% to 30% of the densified composition. Such cermet electrodes can be formed to have electrical conductivities well in excess of 100 ohm-1 cm-1. Other alloy and oxide system cermets having high content metal phases are also expected to be manufacturable in accordance with the invention.
