carbon electrode

Also contains definition of: graphite electrode
An electrode for an electrical application. In its green state it comprises @[email protected] material bound with @[email protected] The @[email protected] material may be either @[email protected], fine-grained or @[email protected] @[email protected] or reclaimed @[email protected] powder. Electrodes for use in steel production can only be manufactured from @[email protected], and the green electrodes are fired at temperatures above around \(2800\ \text{K}\) to produce highly @[email protected] electrodes. The other @[email protected] 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 @[email protected] 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 @[email protected]
