Product description

Graphite rod for electrolysis is conductive materials made from high-quality petroleum coke, pitch coke, etc., through calcination, crushing, kneading, molding, and then graphitization at high temperatures. This process endows them with a unique combination of properties, making them particularly suitable for working in harsh electrolysis environments. They are typically used as the anode, where current flows into the electrolyte, triggering the oxidation reaction.

The wide application of carbon graphite rods in electrolysis is mainly due to their three outstanding properties. First, their excellent electrical and thermal conductivity allows them to efficiently transfer current and dissipate the heat generated by the reaction, ensuring process stability. Second, their excellent corrosion resistance allows them to resist the erosion of many acidic and alkaline electrolytes, resulting in a long service life. Finally, its excellent mechanical strength and machinability are sufficient to withstand the mechanical stresses during production and installation, and it can be easily processed into the required shapes. The combination of these three factors makes it a highly cost-effective electrode material.

Carbon graphite rods are used in many key industrial sectors. In the chlor-alkali industry, they are used as anodes to electrolyze brine, producing chlorine, hydrogen, and caustic soda, which are essential to our daily lives. In metal smelting, they are a core component of electrolytic cells for producing light metals such as aluminum, magnesium, and lithium, especially in the Hall-Hérou process for aluminum production, where large carbon graphite anodes are consumables. Furthermore, they play an important role in electroplating and water treatment (electrolytic sterilization, pollutant degradation).
