Graphite vs. Graphene: What's the Difference?
By Janet White || Published on December 3, 2023
Graphite is a naturally occurring form of carbon arranged in layers, while graphene is a single layer of carbon atoms in a hexagonal lattice.
Key Differences
Graphite, a common allotrope of carbon, is composed of multiple layers of carbon atoms arranged in a hexagonal lattice. Graphene, on the other hand, is a single layer of carbon atoms from this lattice.
The layers in graphite are held together by weak van der Waals forces, allowing them to slide over each other easily. However, graphene, being only one layer thick, exhibits unique electronic and mechanical properties.
Graphite is used in pencils, lubricants, and as electrodes due to its electrical conductivity and layered structure. While, graphene, with its remarkable strength and conductivity, has potential in electronics, composites, and energy storage.
Graphite is a naturally occurring mineral found in metamorphic and igneous rocks, while graphene is typically produced synthetically through methods like chemical vapor deposition.
The electrical properties of graphite, such as its ability to conduct electricity, are less pronounced than those of graphene, which is an excellent electrical conductor.
