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.
Note:
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]
