There is a common belief that graphite's lubricating properties are solely due to the loose interlamellar coupling between sheets in the structure. However, it has been shown that in a vacuum environment (such as in technologies for use in space), graphite is a very poor lubricant. This observation led to the discovery that the lubrication is due to the presence of fluids between the layers, such as air and water, which are naturally adsorbed from the environment.
The lubricating property of graphite is a physical property. The graphite does not undergo a chemical change when used as a lubricant.
No, graphite is a form of pure carbon, an element.
No, graphite is not considered a gemstone. It is a form of carbon that is commonly used in pencils and as a lubricant due to its softness and ability to leave marks on surfaces.
Graphite is not rare as we know it. Graphite is an allotrope of the element carbon, and carbon is relatively abundant in the earth's crust. You can read more here: http://en.wikipedia.org/wiki/Graphite
Carbon graphite is commonly used in electrodes for batteries, brushes in electric motors, lubricants, and as a structural material in high-temperature applications due to its excellent thermal and electrical conductivity, as well as its lubricating properties. It is also used in the production of crucibles and molds in the metallurgical industry.

Very fine graphite powder is used as a lubricant in many applications including locks.
Graphite has a planar structure.
graphite is used as lubricant in machinery.also it is used in making leads of pencils.hence graphite is useful.
Graphite is a form of carbon that makes a good lubricant due to its layered structure, which allows for easy sliding between layers. When used as a lubricant, graphite reduces friction between moving parts and provides long-lasting and effective lubrication.
Graphite has a planar structure.
Graphite is used as a lubricant and, mixed with clay, in pencil lead.
An advantage for graphite is that it can be used as a dry lubricant on electrical appliances.
graphite as a dry lubricant is sold in powdered form in most hardware stores.
The crystalline structure of graphite and diamond are the cause of these properties.
According to Experts, graphite is used as a lubricant because it is dry lubricant and a solid material with a greasy feel which makes for a good source for applications where oil cannot be used. Graphite is used inside pencils. It slips easily off the pencil onto the paper and leaves a black mark. Graphite is also a component of many lubricants.
