What are the components of a pencil core?
Graphite (graphite) is a mineral name, usually produced in metamorphic rocks and is coal or carbonaceous rock (or sediment) formed by regional metamorphism or magmatic intrusion.
The main component of graphite C, he is an allotrope of carbon.
Graphite is an allotrope of elemental carbon around each carbon atom attached to three other carbon atoms arranged in a plurality of hexagonal honeycomb, each layer between the Fan Dehua gravitational weak. Since each atom emits an electron, the electrons are free to move, so the graphite belongs to the conductor. Graphite is one of the most soft mineral, opaque and feel greasy, color from black to gray iron, the shape of a crystal, thin, squamous, striped, layered or scattered in the metamorphic rocks. Chemical properties are inert and corrosion resistant.
