Common Questions About Graphite & Carbon Products
What is an Electric Arc Furnace (EAF)?
An electric arc furnace uses high-voltage arcs between electrodes to melt scrap steel or other materials — reaching temperatures up to 1,800°C in industrial settings. It’s an energy-efficient, scrap-driven alternative to traditional blast furnaces.
How Does a Blast Furnace Work?
A blast furnace is a tall, steel-lined structure used to convert iron ore into molten iron by combining it with limestone and coke under intense heat. It operates continuously, making it an efficient and cost-effective method of iron production — though it comes with high energy demands.
What Is Graphite And What Is Graphite Made Of?
Graphite is a naturally occurring or synthetically produced form of pure carbon, where atoms are arranged in layered structures. This structure gives graphite its unique properties — high conductivity, thermal resistance, and malleability. Synthetic graphite, made by heating carbon-rich materials to over 4000°C, is purer and more consistent than natural graphite.
Why Are Carbon Electrodes Used In Electrolysis?
Carbon (especially in the form of graphite) is an excellent conductor with a high melting point and chemical stability — making it ideal for electrolysis. It facilitates efficient electron transfer at high temperatures and is cost-effective, durable, and widely available.
Why Are Electrodes Made Of Graphite?
Graphite’s unique structure — with layers of carbon atoms and freely moving delocalized electrons — makes it an excellent conductor of electricity. Its high melting point, chemical stability, and cost-effective availability also make graphite ideal for electrode applications in electrolysis, EAF steelmaking, and industrial processing.
Why Are Graphite Electrodes Used In Electrolysis?
Graphite electrodes are widely used in electrolysis because of their excellent electrical conductivity, heat resistance, and affordability. Their layered carbon structure contains freely moving electrons (delocalized electrons), allowing electricity to flow efficiently — even at high temperatures.
