In this process, agglomerated graphite grains are produced for use as carburizer and carbon additives. Intercalation. Due to its extreme anisotropy, the graphite crystal enables salts to be intercalation in its structure. When heated, these salts evaporate, causing the disruption of interplanar connections, "expanding" the graphite.
Production Process. Graphite electrode is a kind of high temperature resistant graphite conductive material made of petroleum coke, needle coke, pitch coke, coal tar pitch,etc. The main production process are extrusion forming, baking, impregnation, secondary baking, graphitization etc. Kneading;
