The answer is Kaolin.
What is the mineral used in the pencil that you write with? Graphite.
Clay is not a rock or a mineral by itself. It is a type of soil material composed of very fine particles that are derived from the weathering of rocks. Clay minerals are the specific minerals that make up clay.
Kaolin is a type of clay mineral that is formed primarily from the weathering of aluminum silicate minerals like feldspar. It is commonly used in ceramics, paper coating, and pharmaceuticals due to its fine particle size and white color.
The primary ingredients are kaolin and petuntse (hard paste) or some other clays.
The average percentage of mineral matter in soil typically ranges from 40% to 60%, depending on the type of soil and its composition. Mineral matter includes inorganic materials such as sand, silt, and clay that make up the bulk of soil particles.
Graphite is the mineral that is used to make the lead in a pencil. Despite its name, pencil "lead" is actually composed of graphite mixed with clay.
The mineral is graphite.
Graphite, a form of carbon
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.
To make it harder. Pure graphite would be too soft for use as a writing pencil.
A "pencil lead" is a mixture of the graphite allotrope of carbon mixed with clay and baked hard. While a pencil lead will conduct electricity, it can not be used to make a light bulb.
What is the mineral used in the pencil that you write with? Graphite.
Graphite is the mineral that is used to make pencil lead. It is a form of carbon that is known for its ability to make marks on paper.
white clay or Kaolin (which is a clay mineral with the chemical composition Al2Si2O5(OH)4). Other materials mixed with China clay to make porcelain clay have included feldspar, ball-clay, glass, bone ash, steatite, quartz, petuntse and alabaster.
Graphite is what is put inside a pencil. The outer casing of a pencil is usually wooden.
it is mixed with clay to form cement.
pencil lead is not charcoal but rather graphite molded with clay and hardened
