Electrode paste, also known as as anode paste, self-baking paste or electrode carbon paste, is produced from calcined petroleum coke (or calcined pitch coke, electrically calcined anthracite coal), calcined anthracite, coal tar pitch and other additional materials. It comes in a variety of shapes: cylinders, eggs, briquettes and polygonal blocks. It is often used in ion alloy furnace, calcium carbide furnace and other ore-smelting electrical furnaces as conducting material.
In addition, as furnace model various, electrode paste for closed type submerged arch furnaces is called as sealed electrode paste, sealed paste for short; while electrode paste for open type or semi-closed submerged arch furnace is called as standard electrode paste.
- Excellent thermal and electrical conductivity.
- Low resistance and low porosity.
- High temperature resistance, low coefficient of thermal expansion.
- High mechanical strength.
