What is graphite and what do you use it for?

Because it is a solid material, it is known as a dry lubricant. This is useful in applications where “wet” lubricants, such as oil, cannot be used. Graphite is the only non-metal element that is a good conductor of electricity. Natural graphite is used mostly in what are called refractory applications.

Graphite is used to make pencil lead, which helps us in everyday life for writing in school, work, home, wherever you need to write something down.
Hope this helps!
