Graphite rods are cylindrical or rectangular-sectioned棒状材料 made primarily from high-purity graphite, formed through isostatic pressing, molding, or extrusion, followed by high-temperature sintering. The hexagonal crystal lattice structure of graphite imparts its high-temperature resistance, electrical and thermal conductivity, and self-lubricating properties, making it widely used in industrial heating, electronics, metallurgy, and chemical industries.
