carbon electrode

Also contains definition of: graphite electrode
An electrode for an electrical application. In its green state it comprises @G02682@ material bound with @P04677@. The @G02682@ material may be either @N04095@, fine-grained or @I03353@ @C01142@ or reclaimed @G02684@ powder. Electrodes for use in steel production can only be manufactured from @N04095@, and the green electrodes are fired at temperatures above around \(2800\ \text{K}\) to produce highly @G02684@ electrodes. The other @G02682@ materials may be used for aluminium electrodes where the duty is not so severe, and the green electrodes are generally fired to lower temperatures.
In both cases it is essential that the granular carbons and the @P04677@ binders used in the production of the green electrodes have a low sulfur content as the release of sulfur during the high-temperature firing can lead to the production of significant @P04762@.
