A paste that binds solid carbon materials with a binder and begins to soften at about 60 ℃. The raw materials for making electrode paste include solid carbon materials and adhesives. Solid carbon materials include anthracite, coke (metallurgical coke, petroleum coke and asphalt coke) and graphite electrode chips (graphite). Anthracite is the main raw material of electrode paste, which can improve the quality of electrode paste. Coke is used to improve the conductivity and thermal conductivity of the electrode. Binders include asphalt and tar (or anthracene oil). Adding tar or anthracene oil to the asphalt of the binder is mainly to adjust its softening point. The electrode paste decomposes and discharges volatiles during sintering, and the residue turns into
