We’ll discuss the F graphite pencil below:
F graphite is a material from which graphite is mined. It often has an oxide-bearing structure at the very center, which has the chemical properties that lead pencils are built upon:
The term “f” is derived from graphite, as it was coined by the French mathematician Pierre J. J. Dubois. From the Latin “f,” a term used to refer to any mineral (as well as to any material) made of more than one element, and “b,” it stands for “bite.” It is also the same Latin name as the word for an insect.
I prefer the term “foil,” as it is less confusing.
F graphite is mined from natural deposits (for example, deposits in a lake or some other body of water). Sometimes mined through the use of water pumps. Other times, it is mined from mined deposits on underground mines. Some areas of the earth have deposits of the material but it is not commercially mined there.
F graphite does not have to be mined to make a graphite pencil. The only requirement is that the graphite be placed around a bend in the pencil. Typically, the graphite is inserted between the bends. This gives the shape of the pencil.
A variety of chemicals are used to make the graphite bend look like a graphite pencil. These chemicals work by forming a thin layer of polymerization that is deposited on the bend’s surface and will eventually grow to a size needed. This process is known as bonding, and it is done by the use of acids, bases or even alkali.
How much graphite does it take to make a pencil?
It varies quite a bit. To figure out the approximate amount, we’ll use one pencil to draw the following figure:
This one will take the pencil about 4-6 grams (3-5 grams) of graphite each.
Let’s look at how this graphite pencil compares to other types I’ve discussed earlier. They are all of the following different types of pencils:
Pencils with a “thin” or “thin-ish” graphite core
Pencils with a “wedge tip” graphite core
Pencils made using graphite oxide and non-solid graphite core
Pencils that are all-solid or a “super thin” graphite core
