FIELD: electricity.
SUBSTANCE: invention relates to the graphite electrode comprising the housing (12) having the axial direction and the radial direction, the housing having the outer cylindrical surface (14) and two ends, one or more ribs (30) circumferentially along said outer housing surface, the sheet (26) of compressed particles of exfoliated graphite on said outer surface. The portion of said graphite sheet is located between said ribs, and wherein said portion has the density of less than 0.5 g/cm3.
EFFECT: graphite electrode exhibits resistance to oxidation as a result of modification of the external characteristics of the cylindrical surface.
