(graphite used as electrode)
A: Graphite is used as an electrode due to its high electrical conductivity and thermal stability. It also resists chemical reactions, making it ideal for applications like electrolysis.
A: Graphite’s layered structure allows free electrons to move easily, enabling conductivity. Its high melting point and durability in extreme conditions further enhance its suitability.
A: Graphite electrodes are widely used in metallurgy (e.g., steelmaking), lithium-ion batteries, and electrochemical processes like aluminum production due to their efficiency.
A: Unlike metals, graphite doesn’t melt or corrode easily at high temperatures. It’s also lighter and more cost-effective for large-scale industrial applications.
A: Yes, graphite electrodes can often be reused after minor repairs. Recycling processes also recover graphite for reuse in batteries or other industrial applications.
