What are the uses of graphite electrodes?
Iron and steel industry: In the steel industry, graphite electrodes are mainly used for electric arc furnace steelmaking. Electric arc furnaces use the arc generated between graphite electrodes and charge to melt metal to achieve the purpose of refining molten steel. Graphite electrodes play a dual role of conductivity and high temperature resistance in this process, ensuring the smooth progress of the electric furnace steelmaking process.

Battery industry: Graphite electrodes are also an important raw material for lithium batteries and lead-acid batteries. In batteries, graphite electrodes, as negative electrode materials, can store and release a large amount of electrical energy. Its excellent conductivity and stability help improve the performance and life of batteries.
Semiconductor industry: Graphite electrodes are mainly used in the semiconductor industry for the growth of wide bandgap semiconductors such as silicon carbide and gallium nitride. These semiconductor materials grow on graphite electrodes and can be used to manufacture high-efficiency electronic devices after processing.
Aerospace field: Due to the excellent high temperature resistance and chemical stability of graphite electrodes, they are also widely used in the aerospace field. For example, graphite materials can be used to manufacture rocket engine nozzles and aircraft brake pads, and their excellent performance can ensure safe and reliable operation in extreme environments.
