Abstract
The present invention provides a Ti3SiC2 based material that exhibits excellent arc resistance, an electrode, a spark plug, and methods of manufacturing the same. A Ti3SiC2 based material according to the present invention includes Ti3SiC2 as a main phase, the Ti3SiC2 based material having a TiC content of 0.5 mass % or less and an open porosity of 0.5% or less. It may be preferable that 0 to 30 mol % of Si in the main phase Ti3SiC2 be substituted with Al. A spark plug according to the present invention includes an electrode formed using the Ti3SiC2 based material.
