An electrode material that may be used in spark plugs (10) and other ignition devices including industrial plugs, aviation igniters, glow plugs, or any other device that is used to ignite an air/fuel mixture in an engine. The electrode material is a metal composite (100) and includes a particulate component (104) embedded or dispersed within a matrix component (102) such that the metal composite has a multi-phase microstructure. In one embodiment, the metal composite (100) includes a matrix component (102) that includes a precious metal and makes up about 2-80%wt of the overall composite and a particulate component (104) that includes a ruthenium-based material and makes up about 20-98%wt of the overall composite. |
