It is a type of pencil that is produced using graphite. The pencil is made from a specially formed polymer which is then filled with liquid or gel graphite (which is called “fine graphite”) and filled with lead. To make a graphite pencil, which does not contain any lead, the lead is dissolved in hydrogen peroxide. The result is an artificial graphite pencil that takes advantage of one of the many properties of graphite.
How can graphite pencils be used for drawing?
Like most natural graphite pencils, the pencil in its natural state is very soft. It is very hard, though, when made of graphite. Because of this hardness, making a pencil with it is very difficult. Therefore, one does not draw on a graphite pencil, for that they need special tools. In addition, when a graphite pencil is used, it will absorb carbon (carbon dioxide) while writing. Carbon dioxide forms a solid film, which is what makes the carbon graphite pencil harder. In fact, it is so hard, this carbon film cannot be removed during normal use. It would take such a pencil that was made of a very soft graphite material to be used to draw anything. Instead, they are used for tracing. The graphite pencil will absorb the carbon before it is lost as carbon dioxide.
How can carbon dioxide be removed during normal use of a graphite pencil?
In most cases, carbon dioxide can be removed during normal use of a pencil because of the way that carbon dioxide gets into the pencil and its resistance to removal. Carbon dioxide enters the pencil body and, as there is no air in the pencil, it can only be removed by the action of the air inside the pencil and surrounding air. Therefore, carbon dioxide can be removed by the pencil itself.
Why does my graphite pencil have carbon dioxide in it?
Carbon dioxide can form a solid film on the graphite while in use. As shown here, the film is a layer of carbon dioxide that is trapped by the graphite. When the gas is trapped, it has to come out. The graphite is therefore very resistant to removal.
Can the carbon dioxide be removed when the pencil is written?
The problem with the carbon dioxide in a graphite pencil is that it comes out. So, after writing, one should use a soft pen. When it is written, all the carbon dioxide is removed. This would be the only appropriate method
