Electrically calcined anthracite (ECA) is manufactured by heat treating high grade anthracite coal in an electrically "fired" calcining furnace. ECA is heated to temperatures as high as 2000 C, which results in some development of graphitic structure in the finished product. When compared to conventional anthracite coal, ECA has high carbon content and relatively high thermal and electrical conductivity compared to un-calcined anthracite. As a result of the unique processing used to manufacture this material it has low moisture, volatile, and sulfur content. Electrically calcined anthracite can be used in the manufacture of Prebake electrodes, Soderberg and tamping pastes, and carbon blocks. ECA is also an excellent smelting additive due to its high purity and consistency.
