Graphite: Background and Summary
Graphite is a naturally occurring mineral that is composed of carbon atoms arranged in a hexagonal lattice structure. It is a soft and black substance that is commonly used in pencils. Graphite is easily identifiable by its dark color and the way it leaves a mark on paper when used in a pencil. When rubbed against a rough surface, it leaves a gray streak. The mineral is also known for its metallic luster and its ability to conduct electricity.Graphite has a wide range of uses in various industries. It is commonly used as a lubricant due to its ability to reduce friction. It is also used in the manufacturing of batteries, fuel cells, and electronic devices. Graphite is used in the production of steel as a carbon additive and in the production of refractory materials. It is also used in the aerospace industry as a material for heat shields and brake linings.
