Graphite electrode

摘要

A graphite electrode exhibits oxidation resistance by modifying the outer radial surface characteristics. The outer radial surface may be modified by providing a textured portion which improves water flow while minimizing water absorbtion. Alternately, a layer of flexible graphite or plurality of particles of exfoliated graphite may be disposed on the outer radial surface of the electrode body.

主权项

1. A graphite electrode comprising:
a body having an axial direction and a radial direction and further having an outer radial surface and two axially opposed ends; a groove disposed along the outer radial surface extending substantially from one end to the other end; a sheet of compressed particles of exfoliated graphite disposed around at least a majority of the outer radial surface; a portion of said sheet of graphite being disposed in said groove; and wherein said portion has a density of no more than 0.5 g/cc.
