Carbon C
Graphite is an allotrope of carbon and is a naturally occurring mineral.
Applications
Pencil Lead
Lubrication
Conductors and high temperature applications
Heaters
Crucibles
Anodes in batteries
Properties
Graphite has good lubricant properties both in the dry form and when suspended in oil. It is chemically very stable and almost inert. Graphite conducts electricity and is a good conductor of both sound and heat. It is anisotropic so conducts in one direction. It is insoluble in organic solvents and water and has a high melting point of 3650 degrees centigrade.
