The mineral is graphite.
Graphite is the mineral mixed with clay to make pencil lead. It provides the dark pigment needed for writing and drawing and is a popular choice for its smooth writing properties.
The mineral mixed with clay to make pencil lead is graphite. Graphite is also used as a lubricant for machine parts and as electrodes in batteries due to its ability to conduct electricity.
The "lead" of a pencil is made from graphite, which is a form of carbon.
The formula for pencil lead is a combination of graphite mixed with clay. The most common type contains graphite and clay in a ratio of approximately 80:20. The clay acts as a binder to hold the graphite together and determine the hardness of the lead.
Pencil "lead" is actually made of graphite, which is a form of carbon. The graphite is mixed with clay to give it form and strength. These mixture of graphite and clay are then encased in wood to create a pencil.
Graphite is used as a lubricant and, mixed with clay, in pencil lead.
Pencil Tip is made of Lead, but nowadays it is usually made of Graphite.
What is the mineral used in the pencil that you write with? Graphite.
Pencil "lead" is actually made of a mixture of graphite and clay. The exact ratio of these components can vary depending on the desired hardness of the pencil lead. The components are mixed together, heated, and then formed into the shape of the pencil lead.
Pencil lead is a mixture of graphite (or other colored pigment) and a binder (e.g. clay, wax, plastic, grease).
