Electrically Calcined Anthracite Coal (ECA Coal)

ECA CoalECA coal is manufactured by heating high-grade anthracite coal to temperatures as high as 2000ş C in a DC Electric Calciner obtaining a devolatized and semi-graphitized product. ECA has a higher carbon content and relatively higher thermal and electrical conductivity than conventional anthracite coal. Calcining is controlled to achieve a significant lower Electrical Resistivity (E.R.- µΩm), ranging from 550µΩm to 750µΩm depends on customer’s needs. Our ECA has low moisture, volatile and sulphur content. It can be used in the manufacture of prebake electrodes, Soderberg and tamping pastes, and carbon blocks and is an excellent smelting additive due to its high purity and consistency.

Application:
It is the main raw materials for manufacturing carbon electrode paste and also widely used in Aluminium & Steel Industry.
