GRAPHITE (REGENERATED) CRUCIBLES
Graphite (regenerated) crucible specifications and physical and chemical indicators
Graphite (recycled) crucible is a new material product used for the production of negative electrode materials for lithium batteries. It is made of high-quality petroleum coke and coal tar that have been graphitized at 2800°C, and is molded, baked and machined. It has good thermal conductivity. In high temperature use, it has the characteristics of small thermal expansion coefficient, thermal shock resistance and low friction factor. It is mainly used for purification and purification of negative electrode materials of lithium batteries and refining and purification of non-ferrous metals and new materials.
