ABSTRACT: Carbon graphite is a crystalline form of carbon consisting of layers of
hexagonal carbon atoms arranged in a two-dimensional “graphene” structure. Graphene layers are stacked on top of each other,
forming a three-dimensional structure with a high degree of anisotropy.
The carbon atoms within each layer are linked together by strong covalent
bonds, creating a strong, stable lattice structure. However, the layers
themselves are held together by weak van der Waals forces, enabling them to
slide easily over each other. The properties of carbon graphite are highly
dependent on the orientation and alignment of the graphene layers. When the
layers are aligned parallel to each other, the material exhibits high strength
and stiffness along the alignment direction, but is weaker and more flexible in
other directions. Carbon graphite is used in a variety of applications where
high strength, rigidity and electrical conductivity are required. Some common
applications include electrical contacts, electric motor brushes, and as a
structural material in aerospace and defense applications. The aim of our work
is to describe the structure of graphite, its physical and chemical properties
and its applications.
